You are aware that gas prices are pretty high right now and we're having pretty shitty economic times on top of it? Yet people are still buying and driving SUVs.
Now I don't have a P.H.D. in economics but it seems to me that if you were to raise the gas taxes high enough to get any significant portion of the SUVs off the road right now, you would jack the prices on everything shipped by truck to a level just as uncomfortable. And inhibit consumer spending. And drive us most definitely into a double-dip recession.
Then again, all the unemployed people would lose their SUVs and have to go about their starving on foot, so I guess it would help even more. For a really fucktarded definition of 'help'.

You are extremely naive.
