See that’s where I fully disagree with you - I am not signing up for fully autonomous cars everywhere. If people want to buy them go ahead but everyone losing their ability to drive for any “greater good” is the absolute opposite. It eviscerates freedom of movement for people who have had the joy of that for the last 80 years or so. Don’t have the latest medical intervention? Sorry your car won’t work because you don’t have a steering wheel and the navigation is locked. That’s not a world I’m signing up for.
By the datapoints I am also meaning what these cars have already seen. Simply people walking around messes them up. Putting one of those self driving cars in rush hour street traffic in a big city like New York, Miami, Houston and you have hundreds of people walking around, crossing streets and lots of other things going on. It’s much different than a plane, and something they may eventually get better but it’s highly complex environmentally.
