As far as the bumper stickers, I've come to the conclusion that the people that put those on their cars do so because they are largely the people that create all of the traffic problems. Of course they want you to coexist because they have a ton of nonsense they know people will have to put up with. Making it your problem is their best solution.

Grey - as far as this crap happening stateside, I can tell you there is a point where the average American hits back. I don't think we're there yet, but France seems to be awfully close.
