Would it be too implausible to create the present day without the invention or proliferation of personal vehicles? Like if Henry Ford hadn't invented the Model A or the country went full government-run public transportation. In my story, my MC is a lobbyist for personal vehicles. He is meeting heavy resisitance from congress and the current president in trying to legalize cars. The problem is that the general public can't imagine a 2,000 pound hunk of metal travelling 60 miles-per-hour mere feet from another vehicle going in the opposite direction. The feeling is that the average American isn't responsible enough to handle that kind of responsibility. Would it be too much to veer off the horse->cart->buggy->car timeline and take it in a different direction?
