As I'm sure you know, mmac, the more expensive gas in Europe is because of taxes. Of course, those taxes then support things like effective mass transit.
This might be the proverbial wakeup call (though I doubt it: the gas shortages of the '70's didn't work, rising prices haven't worked, even wars where oil fields are a factor haven't worked). Too many Americans use gas as if an infinite supply was their right.
IMO, lone drivers in massive SUVs (most particularly in the city) are an advertisement for selfishness. Of course there are reasons to drive an SUV if you pull a trailer regularly or are actively involved in the construction industry, but they're hardly required for the overwhelming majority of US drivers.
Don't even get me started on Hummers. Particularly the ones with the odd sense of humor to include an "I support our troops" bumper sticker.
