How does the auto industry having problems lead to less cars on the road? It's a complete non-sequitur. They'll buy foreign cars, or used cars. The only result would be maybe more older cars putting out more pollution.
Personally, I'm done with buying new cars anyway; I think it's a sucker move. Anyone who's at all handy (and if they're not, they can teach themselves) can buy a used car for pennies on the dollar and keep it running until it rusts away for not much money. I've got a friend who's been driving a $400 Saturn for 5 years now. It looks like ****, but he (and I) don't require our possessions to scream to the world how great we are. I actually kind of like to drive old heaps, they have personality.
