Aside from the little problem of putting more money than necessary in the hands of our enemies which you refuse to acknowledge, there's another problem, and that problem might not even exist in California, which I assume is where you are writing from, but it's a fact of life on the East coast.
The problem is that if SUVs were the occasional vehicle here and there, they would not obstruct everybody's vision in dangerous ways but, when one out of three or one out of four vehicles in the daily rush hour is a van or SUV, then nobody including the SUV and van drivers can ever see further than one or two cars in front of him, and that is dangerous.
The question is not individual rights. The question is, do you and other SUV owners have some sort of a group right to endanger yourselves and everybody else in such a manner?
Like I say, the guy driving an SUV off road, on a hunting trip, to the beach or whatever does not bother me. It doesn't consume that much gas or cause that much danger. The guy driving an SUV with three or four people in the HOV lanes does not bother me either. The guy driving an SUV as a commuter vehicle with just him, which appears to be most of them, I would tax into tommorrow.
