my point is that "if there's an obstruction, stop" means these cars are going to be stopping and requiring human intervention all the time. That's semi autonomous at best.
I don't know if you've encountered intransigent geese in your driving adventures, but the only way to deal with them is to slowly drive through the flock until they move out of your way.
fully autonomous cars are never going to happen without major changes to our roads. we'd be better off investing in more busses and trains.
