This applies to mostly any other country in the world as I can't think of anywere where they regulate vehicle sizes. Yet you don't see nearly the same ammount of SUV in the roads. And in fact I think an SUV makes more sense in the third world: road maintenance is generally much worse with potholes everywhere; traffic enforcent much less effective, so speed bump everywhere too; a big truck is probably safer than a small car if you're about to get robbed in the street... the real "tragedy" of the US is people being too rich and things people worry about in other places like gas and financing being so cheap.
