We had self driving vehicles for 30,000 years. I’ve thought about just getting horse brains hooked up - but people probably don’t want their cars spooked by plastic bags.
How do you know the people bullish on self driving cars haven’t also lobbied for trains? There’s a lot more standing in the way of trains being built in the US, unfortunately. To me, self driving cars are just the second-best thing, and one that might actually happen. It’s a bit too late for trains to take over in most of the country.
