Oh, your car can't follow the law? Then it isn't allowed on the road.
Oh, your car broke the law? Owner of the car is liable.
Oh, your car is avoiding being pulled over? Owner of the car is liable.
Oh, it's owned by a company not a person? Owner of the company is liable.
It's a fleet car that will never have a driver, put everything on the CEO. And if there isn't a CEO, pick a random person from the company. And if there ends up not being people at the company, the government now owns them and can do whatever they want with them. And if the government owns a fleet of something that's dangerous to the public and doesn't do anything about it, well then the people have a right to ownership.
If there is no liability, then nobody owns it and it's up for grabs. Autonomous cars aren't fucking dragonflies.
Hard to insure what's always on fire.
