If I may piggyback on Nancy’s (superb!) post, that to me is the problem with $2 gas. I drive much less when it costs $60 to fill up my tank than when it costs $30 (I remember when it cost under $15–yikes!). I drive slower, too. The thing is, even though gas no longer hurts my wallet, it still harms the environment, which, as has been noted several times on this blog, puts the most vulnerable persons at even greater risk. Anyone for a massive fuel tax whose revenue would be invested in green technology rather than Exxon-Mobil’s profits? How about bringing the speed limit back down to 55?
