You didn't say anything about "people want" or "people don't want". > How can a car be to small for your streets when there are bikes and whatever also driving around? Can also be presented as: if bikes are driving on roads, cars can't be too small for roads (because they are bigger than bikes). So, bikes being on streets doesn't mean they are big enough for roads. Your whole sentence is "non sequitur". What I want to say: small cars can be too small for USA roads independently of bikes being too small for USA roads. People wanting to drive small cars or bikes is also independent and being allowed to is also pretty much independent. Now, my opinion: I think you should be allowed to drive small cars, I have a small car too (and a bike), but existing usage of roads in USA by increasingly big cars makes it increasingly unsafe (in USA). I agree that USA should do something about bigger and bigger cars, but I have no idea what and it's not very probable that I will ever drive a car or a bike in a big city in USA, so you can safely ignore my opinion and drive whatever you like.
