Well, I can admit that Ford learned from Honda quite a bit, which could be readily seen in their Focus line. Is it their fault that consumers stubbornly want the likes of F-150 or Chevy Suburban, which are not even proper cars?
Small, inexpensive cars would also be good in some circumstances, but the US auto industry, for some reason, struggles to offer something as compact as Honda Fit, or at least something as reliable as Toyota Corolla.
1) The amount of safety requirements that the US (and additionally CA) make the margins too low to sell cheap cars.
2) Most people don't want them and won't buy them (myself included).
Although I have lived in multiple towns where "golf carts" are legal and those were cool.
Your "need" is a feel good story with 0 chance of ever passing as Federal law, thank god. Pass it in your state if you wish.
