I don’t think SUVs in and of themselves are a problem.
Ever since I was a young man, I’ve typically owned either a truck or SUV. Throughout the 80s I typically had a truck or SUV (back then they weren’t called SUVs–think Broncos and et al.) and would keep it parked in my garage. I’ve usually had a mid-sized sedan for getting around (or in my slightly wilder days a sports car.)
Even back then, I never saw the larger vehicle as my “every day” vehicle. It didn’t make much sense to use it as such, even back in the 80s when gas prices weren’t a huge concern, it was asinine to drive around a big lumbering vehicle. It was nice to own one, for when I needed to haul stuff or the weather turned ugly.
But day to day, a car was easier to move around, lighter on the wallet, and just generally less of a pain to drive.
Sometime in the mid 1990s, SUVs transformed from vehicles guys like me used to haul stuff or go off-roading in, to vehicles soccer moms used to haul groceries and sometimes kids. Often times these land-yachts are driven around with one or two people in it, with seating for 6-7+.
If you actually drove vans/SUVs with full passengers they are are much more efficient than even the most efficient hybrid. Sure, the MPG isn’t great, but if one vehicle can be used to combine five individual’s commute that one vehicle, even if it gets poor gas mileage, is way more efficient.
It’s sort of the idea behind buses, they don’t get great gas mileage, but they haul enough people that they’re still more energy efficient than the most efficient hybrid, when you compare that one vehicle’s gas usage to the gas usage of all its passengers were they to drive themselves separately.
If people got serious about car-pooling, that would drastically alleviate the woes of many.
Realistically, for many it is a financially poor decision to trade in a gas-guzzling SUV, even at $4/gal gas. Because SUVs are so unwanted right now there will be a significant cost at converting from an SUV to an energy efficient hybrid; a cost that you probably won’t make back in saved gas money.
America’s biggest transportation problem is people think their commute should be a time of quiet sanctuary, we have way too many people riding alone to work. Many married couples could work out a way to use one car a day to commute, for example. I know many couples who work at roughly the same time, and don’t work so far apart that sharing a ride would be unreasonable, but they all drive themselves. The only real downside to them driving together would be they’d have to leave a little bit earlier so they both get to work on time.
SUVs in and of themselves aren’t a problem, it is how they are used. For the vast majority of Americans, SUVs should never have become a primary transport. Most SUVs are as bad as worthless for off-roading, but they are nice in poor weather in rural areas.
