> Large vehicles are important part of American economy and mostly driven by blue collar workers doing their work. For example things like plumbing, construction site work etc.

So explain the difference between the twentieth century (and the first few years of the twentyfirst), when trucks were an exception and cars were the norm, and now. Are you saying there were almost no plumbers and construction workers around then, or that almost everyone is a plumber or construction worker now?
