SUVs Are Killing Pedestrians

 SUVs keep growing in popularity in America. Also, accidents in which pedestrians are struck by vehicles have been increasing. Now, connect the dots.

What connects the dots is a study that shows that SUVs—and pickup trucks, which are also gaining in popularity—have a significant zone immediately in front of them where something in the road would not be visible to the driver. This is because their hoods are higher.

So, owning and driving an SUV puts pedestrians at greater peril; not to mention the fact that SUVs have a greater impact on the environment. They burn more fuel, on average, than cars and thus emit a greater quantity of greenhouse gases.

The American road is on track to become nearly all SUVs as the major American car makers are dropping their sedan models. There is sort of a push-pull operating here: The car makers claim that buyers demand SUVs, but SUVs are more profitable to build, so auto makers are more than happy to switch their product lines, more and more, to SUVs. You cannot any longer buy a sedan from Ford or Chevrolet, both of which built several good small sedan models.

SUVs are not as popular in Europe. I frankly don't understand why they are so appealing to drivers, but one theory I have is that, as American cars grew smaller (look at, for example, the length of '60s cars and compare that with more recent models), people reacted against that by finding large vehicles in the form of SUVs.

Climate Change/Global Warming

One of the reasons I'm rather pessimistic about the prospect for our world's beating the global warming/climate change problem is that not enough is being done about it. We hear the world's politicians talk about it but any action being taken is at some point going to be seen to have been too little, too late.

Americans (for one) don't appear to be changing their habits, and I don't really hear anyone urging them to. Where are the leaders urging people to drive less? To not buy big and thirsty SUVs? (The equation is simple: more fuel consumed = more greenhouse gases being emitted.) And who has—or would have—the bravery to discourage Christmas lights in the name of saving energy? Anyone who did so would be accused of being anti-religion or even anti-God (show me where in the Bible we are commanded to string electric lights upon our houses to celebrate the birth of Christ).

Electric vehicles are expected to do much to reduce production of greenhouse gases; but so far, in most countries, the penetration of EVs into the car market has been rather insignificant--on the order of 3% to 6% of car sales. One reason is that electric cars suffer from a serious price disadvantage. And, I do not see any great numbers of charging stations in my area. On the other hand, "range anxiety"--the fear of drivers that they will be traveling and their car's charge will be running out when they are not near any place where the car could be charged--might be diminishing because electric cars' range (on a charge, that is) has been increasing.

I myself have given some thought to getting an electric car. If I got one it would probably receive all or nearly all of its charging in my garage. But, to have and use only 110 V charging is very slow; and to install a faster, 220 V charger in my garage I'd have to buy a charger and pay an electrician to wire it into my house wiring--for a total cost of nearly $1000. 

I'm sure electric cars are the wave of the future, but it's going to be a while before they are truly common. Better, cheaper, lighter-weight batteries must be developed, and I don't think anyone is sure when that will  happen.

Another thing, on a somewhat different note: Rainforests, as we hear often, are a very important repository of carbon, and cutting down and/or burning these trees not only reduces the amount of carbon that can be absorbed from the atmosphere, but the burning of the trees releases carbon that has been locked up perhaps for centuries. Yet in Brazil, the trees of the Amazon rainforest, one of the most important on the planet, are being cut down and burned, to make room for pasture land or farmland (e.g., plantation of palm trees for the palm oil that is showing up in so much of our food)--not to mention that this process is depriving indigenous people of their land and homes. Yet Brazil's President Bolsonaro does nothing to stop this pillaging and destruction of the rainforests of his country.

In many nations there are conferences, there are speeches. But is enough being done, aside from talk? At least a few scientists warned of the problem decades ago. True, we have some renewal energy--wind farms, etc.--but they still are providing only a small percentage of energy consumed. We need "transformative" change, and it doesn't seem to be happening.

Your SUV Is Helping to Destroy the Planet


Transportation in the US--that includes all our cars plus, of course, trucks, buses, and so forth--is responsible for 20% of greenhouse-gas production. (And, as nearly all scientists will tell you, greenhouse gases produced by burning fossil fuels contribute to climate change.)

And people do not realize that, when they buy a big SUV that is thirsty for gas, they may be producing more than their share of CO₂.

The equation is very simple: More gasoline consumed equals more greenhouse gases out the tailpipe.

So, please, to avoid doing your share to destroy the planet, please think twice when purchasing that SUV. Ask yourself whether you really need such a big one, and look at the gas mileage of any model you're considering.

Suburbanites and SUVs

This is perhaps two essentially separate subjects, but the connection is "the suburbs."

I saw a statistic, several years ago, that showed that half of all Americans live in suburban communities. Many of these children grow up unfamiliar with the downtowns of their cities: frequently, maybe not atypically, they get to see the city only on rare school field trips. I think that's unfortunate because the city, especially the city's downtown, tends to be where the cultural resources--museums, orchestras, etc.--are. You're likely to have more exposure to these things if it doesn't take an expedition to get to them.

They grow up with the perception that the city is dangerous and crime-ridden. Because of their limited, suburban childhoods and this (hopefully erroneous) stereotype, when they grow up they replicate the pattern and often would not even consider living "downtown" but only in suburbs. So the suburban adults may go downtown for their jobs, but hurry to get home via their commuter trains once the work day is over. Outside of working hours they are never to be found downtown. On the weekends, here in Chicago, the people that you see downtown are probably tourists.

If the culture is downtown, the suburbs may tend to have an insular mentality. I live in a suburb (I'm tempted to say "unfortunately") and at one  point was attending a weekly group that views and then discusses a film each week. I have tried to circulate among this group the calendars of some theaters and other film venues that are downtown or on the North side; but like good suburbanites, they pretty much will not seriously consider traveling out of their area, or perhaps it's out of their comfort zone.

The suburban kids' families probably own an SUV. So as children they rode around in an SUV (or, if not, then probably a minivan). They might even have taken their driving lessons in a small SUV. So, in a manner analogous to the address of their residence in their early and formative years, their idea of what is normal and what they should emulate when it comes to their own vehicle purchases once they're adults is such that they may not consider anything other than an SUV.

I think that's unfortunate, and I hate to see an SUV culture perpetuated from generation to generation. Readers of this blog may know that I hate SUVs and can give numerous reasons for that, but one that I feel strongest about has to do with ecological concerns. Americans with their large SUVs are harming the environment. It's not simply a matter of depleting the store of fossil fuels. More fuel consumed means more greenhouse gases out the tailpipe, so that large SUVs make a larger contribution to global warming.

We are beginning to hear from safety experts that driving while talking on a cell phone is dangerous, yet one sees that an awful lot. It makes me nervous when, in my rear-view mirror, I can see the driver behind me talking on a phone. It makes me fear getting rear-ended if driving is not the primary focus of that person's attention.

Many large SUVs weigh three tons (6000 lb, 2700 kg). I don't think that many people driving them consider that they have a deadly weapon in their hands—or hand! Hand, singular, because they have one hand on the wheel while their other hand is holding a phone. When you're taught to drive you're taught to use two hands on the wheel, and that's because it takes two hands to properly control a car or truck.

You know what I would do, if I could? I see so many drivers making a left turn, steering with one hand while the other hand is otherwise occupied. I'd take away their power steering. If it were appropriately difficult to turn a big vehicle like that—that is, if the effort of steering had some relationship to the vehicle's size—then they'd need two hands to drive. And then, guess what? No more holding that phone.

Update, July 11, 2013
I don't want to be perceived as anti-suburbs. (There are numerous reasons why people might want to live in a suburb, many of which are certainly valid: less expensive housing, avoiding noise and congestion, better schools. I personally moved where I am to be closer to a job I was starting at the time; and I remain here probably for the lower cost of housing. I also appreciate being able to deal with smaller, less bureaucratic and perhaps more responsive government agencies.) I meant to simply lament the fact that suburbanites all too often are cut off from the advantages of the cities that they live near.

The Myth of SUV Safety

I believe many people own and drive SUVs because they believe they are safer. I think that is especially likely to be the case when I see a woman driving a very large SUV. (If she's the sole occupant of the vehicle, as often is the case, I think she's not driving such a vehicle for its carrying capacity in persons or cargo.)

I believe that large SUVs in particular contribute to global warming because more fuel consumed = more greenhouse gases emitted out the tailpipe. But I'll focus here on safety.

A driver who believes that four-wheel drive is necessary—perhaps for driving in snow—should be aware that now many sedans are available with four-wheel drive. Second, I recently learned that four-wheel drive confers an advantage of better adhesion only when traveling in a straight line. It is no help in cornering.

Further, SUVs actually have a safety disadvantage because they are top-heavy and thus more likely to overturn. Twice within two or three days the TV news has shown a picture of an SUV lying on its roof after an accident (this may be coincidental—I don't want to imply otherwise—but they were Jeeps in both cases). Anyone who pays attention to TV news coverage of auto accidents has seen enough photos of SUVs which skidded off the road because of a winter storm or after an accident, and ended up lying in a ditch or lying on their roofs, to be disabused of the idea that they are safer than other types of vehicles.

Update, April 5, 2013. This morning there was an accident in Chicago where a school bus hit one or more other vehicles. One was a Jeep Wrangler, of which the driver was killed. Another Jeep vehicle was involved and I am not certain how the occupants of that vehicle fared.

Update, May 5, 2013. Again today--for the umpteenth time, it would seem--the news included a story of an accident in which an SUV suffered a tire blow-out and overturned. The driver was ejected and killed. Three passengers in the vehicle were injured but not killed.

Why You May Not Need an SUV

Many people are switching to more economical vehicles, giving up their SUV for a car, or perhaps a large car for a smaller car.

Besides high gasoline prices prompting some buyers to think about the fuel economy of the vehicle they're going to buy, two things are going on here.

First, people who feel they need a four-wheel drive vehicle--probably for driving in snow and ice more than through mud or other off-the-road conditions, since studies have shown that few SUV buyers actually ever take their vehicles off-road--realize that they have options other than an SUV, such as four-wheel drive car models from Mercedes-Benz, Audi, Volvo, BMW, VW, Porsche, Acura, Infiniti, Lexus, Mitsubishi, Mazda, Toyota, Honda, Ford, Cadillac, Lincoln, and Subaru (these are not all expensive makes/models!).

Second, small cars have become more appealing. At one time small cars were cheap and were perceived as cheap. Now, small cars can be had with nice appointments like comfortable seats and attractive styling in and out, and as great a choice of options as more expensive makes and models. And, after many unfortunate attempts by the American car manufacturers to produce small cars—"unfortunate" for a variety of reasons, including not taking small cars seriously or the mistaken idea that they could take a larger car and just shrink it--small cars from American manufacturers have gotten much better, and are now decent or even quite good in many of the real "car" qualities like ride, performance, and handling (steering, braking, cornering).

SUVs Are Destroying the Planet

I have written numerous times about how I hate SUVs. I am sure also that I've given numerous reasons and recounted how, in addition to my original reason (they have high headlights that hurt my eyes when they shine in my rear-view mirror), I have pretty much continually found more and more reasons to dislike them.

A couple of my current gripes: Several manufacturers of SUVs (and pickup trucks as well) have begun giving their vehicles very aggressive styling. One manufacturer started it and at least two others have followed suit. Presumably this is a selling point with some buyers; but these vehicles deliberately are made to appear intimidating to other drivers, and especially when one of these is following my car too closely—almost literally driving right on my rear bumper—I do in fact find it intimidating. It's as if that huge thing behind me wants to swallow up my car. (Not to mention that following too closely is unsafe, and it almost ensures that my car will get rear-ended if I should have to stop abruptly.)

And I think that intimidated is exactly what the SUV driver wants to make me feel. In this situation I will sometimes make a gesture to convey to them to "back off"; but sometimes that driver can't or won't get the message. A few of them seem genuinely clueless about how intimidating their vehicle, and their driving habits, are.

And—number two—I believe that SUVs are destroying the planet. Well, they and their owners are doing a lot to destroy the planet.

You don't hear this but my logic, I believe, is unassailable. The greenhouse gases that a vehicle emits are in proportion to the fuel consumed. Therefore, the poor fuel economy (and thus, of course and very simply, a lot of fuel burned) translates to high greenhouse gases emission. (See "Update," below.)

People who drive uneconomical vehicles think (and probably will tell you, if you give them a chance) that if they can afford the gas, their vehicle's fuel economy is their business and no one else's. But then, the people who drive enormous SUVs are probably not "green" people nor people with an acute social conscience.

Update, October 4, 2012.
The new vehicle label from the government (EPA/DOT) displays the statement, "Vehicle emissions are a significant cause of climate change and smog." Of course I am happy to see this information being made more available to car buyers. Also, the new labels give an indication of  just how much greenhouse-gas emissions the prospective vehicle will produce. So now car buyers will be better equipped to contemplate this aspect of the consequences of their vehicle purchase.

Some Points about Cars--Particularly, Are American Cars (Finally) Good Enough?

First, latest vehicle crash test results from the IIHS (Insurance Institute for Highway Safety, an insurance-industry body) show that many small car models fare very well in crash tests. This means that people who have been choosing enormous vehicles like SUVs because these large vehicles are perceived as safer in a crash, can start to consider smaller and more economical vehicles.

Second, a new government window sticker on new cars will begin appearing on 2012 models (and on all cars starting with the 2013 model year). It not only shows city, highway, and combined fuel economy ratings for that vehicle; but will also show (1) expected fuel costs over 5 years; (2) a numerical ranking which indicates how that car compares to other vehicles; and (3) another ranking that gives an indication of that vehicle's environmental impact.

I am particularly happy to see number 3 above, because I don't think that very many car buyers give much thought to the environmental impact that the vehicle they're buying is going to have. But even without the new ranking, there's one very simple fact they might consider: greenhouse gas emissions from a vehicle are proportional to the fuel consumed. Simply put, lower gas mileage (more gas used) means more greenhouse emissions.

Third, domestic cars seem to be getting better—and they had a long way to go, in terms of assembly quality and performance characteristics.

Let's look back quite a ways: There was a popularity for foreign, and particularly British sports cars, starting perhaps around the late 1950s and continuing for maybe two decades. This is supposedly due to American servicemen discovering some of these cars when they were overseas, around the end of WWII, and maybe even bringing them home. These cars offered better performance than American cars and were just more fun to drive.

Now, an important fact to keep in mind: When I talk about performance I'm not just talking about a car having zippy acceleration or higher top speed. Many foreign models also showed better handling characteristics: better cornering, better braking, more responsive steering.

For decades American cars lagged in these qualities (and American car buyers often did not pay attention to them, either). American cars had soft suspensions (springing) that made for a soft but wallowy ride—these cars' noses would dive under braking and they would roll during cornering—which implies poor handling during an abrupt maneuver such as in an emergency. American car makers believed that was what American car buyers wanted--a soft ride even if achieved at the expense of handling characteristics. Intrinsically, the two—ride and handling--are mutually exclusive, although more sophisticated, and inevitably more expensive, suspension designs permit good handling characteristics with less compromise of ride comfort.

Over the years American cars have come to incorporate some more sophisticated mechanical designs, both in their engines and in their chassis. But even when a U.S. car model was based on a European model—and I could give a number of examples of this, from the last 10 or 15 years—that European chassis, with its better handling characteristics, would be "dumbed down" for the American market—that is, ride characteristics would be made softer, sacrificing the car's handling qualities.

Now we're starting to get U.S. cars with decent handling, whether based on European chassis or not. People who value good handling qualities can be glad that now we can get Detroit cars that are more equivalent to European cars.

Let's look at some models that Chevrolet has offered. Their small model at one point was the Cavalier, which was regarded as not a very good car by the automobile press.

That model was followed by the Cobalt. Evidently the Cobalt was better than the Cavalier, but maybe still not good enough, because now we hear that the Cobalt's successor, the Cruze, is better than the Cobalt was.

And Chrysler, until this year, had been offering a model called the Sebring, which was almost universally said to be not a very good car, in many ways. Now the Sebring has been replaced by the 200—which evidently is substantially better than the Sebring but maybe still not good enough.

So I wonder why, in so many cases and for so many years, Detroit—which must know how to make a good car, and undoubtedly employs an awful lot of very competent engineering talent--has been content to make "better but still not good enough" cars. GM (maker of Chevrolet) might just be wising up; and Ford, too, has been bringing out good cars. Chrysler is lagging behind the other two.

My Car Isn't Big Enough

I used to wonder why people drive SUVs. At one point I thought it was to be macho—but a lot of women drive them. (I think the macho factor might hold true for guys who opt for big pickups, muscle cars, etc.) With women, at least, I think the answer is that they feel safer in very large vehicles that put a lot of steel around them.

Admittedly it's true that, in a collision between a small vehicle and a larger one, the small one is likely to get the worst of it. That's simple physics. So the people who are driving monster vehicles are likely to inflict more harm—harm to the vehicle and maybe bodily harm to the driver—when they hit a smaller vehicle.

But they would say, I'm sure, Well, let them drive a big vehicle, like I do. I'd call that a kind of arms race. I'm glad not everyone thinks that way, or we'd all be in vehicles the size of a stretch limo or a tank—or one of those huge Hummers—that would hardly be able to make it around the corner in urban driving.

Well, the price of gas is rising again. It must cost $70—maybe even a lot more (I don't know how big their tanks are)--to fill some of those big vehicles. Let no owner of an SUV, large pickup (when it's not needed for business purposes or work), or van complain to me about the price at the pump, 'cause you know I'm the last one to sympathize with them.

Gas Prices Going up--Again

From my window I can see the price sign of a gas station, so I'm usually up on where gas prices seem to be headed. There was a recent dip that proved very temporary, and prices now are about 30 cents higher than they were during that dip. Said neighboring station currently shows $3.259.

I wonder how high the price of gas has to rise before people who own monster SUVs like Suburbans and Tahoes regret buying such a thirsty vehicle. And you know, if you follow this blog, that I have less than zero sympathy for those folks, because I regard them as destroying the planet. (Greenhouse gas emissions are directly proportional to gas consumption.)

Statistics show that, when gas prices rise, people are interested in smaller, more economical cars. When gas prices fall again, people go back to disregarding fuel economy when they're car-shopping, and in fact sales of large SUVs rise again. (This has been a problem for Detroit at several periods over, say, the last 50 years: They introduce small cars and then the price of gas falls and they can't sell those smaller cars.)

So we see that car buyers can be very short-sighted. The price of gas may fall but it will certainly rise again, kind of like the stock market. And, like the stock market, I'd wager that, long-term, the trend is upward.

More on SUVs

An article on AOL Autos, on the new (2011) Ford Explorer SUV reminds us of all the news that surrounded the Explorer a decade ago, when there were many rollover accidents involving Explorers and resulting in some 150 deaths.

While the tires (Firestone) supplied on the Explorers got a lot of the blame, the NHTSA (National Highway Traffic Safety Administration) stated, after its investigations into the accidents, that driver error may have been to blame.

The fact is, taller vehicles such as SUVs (all things being equal) have a higher center of gravity and will be more prone to roll over. That's simple and inexorable physics. Presumably many of the people who own and drive SUVs are not prepared to take account of their vehicles' handling characteristics, particularly the vehicles' handling characteristics in an emergency situation.

These owners and drivers are not properly aware that they are not driving cars. They think they've got cars but with the ability to absolutely stick to the road on snow and ice. Many have learned, to their sorrow, that that's not the case.

Also, too many drivers of SUVs—as with other vehicles—can be seen driving while talking on cell phones, maybe making left turns with one hand on the wheel. I am sure any driving teacher tries to tell student drivers that a vehicle is properly controlled only with both hands on the wheel. I think that, particularly in the case of SUVs, you have a perhaps three-ton lethal weapon which is not being properly controlled.

So, given drivers' ignorance of SUVs' characteristics or their disregard of those vehicle characteristics, I think there is a job of education that needs to be done. As I said, some of the larger SUVs weigh three tons. They can be deadly weapons, given the harm that can occur to a smaller vehicle when it is hit by a monster SUV, and need to be driven with more responsibility.

SUVs, Oil Demand, and the Gulf Oil Spill

An article on the Gulf oil spill that appeared a couple weeks ago said that it's hypocritical of people to criticize the oil spill or bemoan all the harm done—as long as they themselves are driving their thirsty SUVs that create the oil demand that in turn necessitates drilling in the Gulf.

I have a friend who is very enthusiastic about electric vehicles—should I say "coming electric vehicles"? He forwarded to me an article that mentioned an estimate of how much oil would be saved when we are driving electric cars. Quoting Senator Lamar Alexander of Tennessee, the article says,

Our goal should be to electrify half our cars and trucks within 20 years, which would reduce our dependence on oil by about a third. . . .

That sounds good. But I'd be very curious to know how that would compare with the percentage of oil that would be saved if we could move people out of their SUVs and into reasonably fuel-efficient vehicles.
