But there are already laws governing that. This petition is calling for the cars to be banned until new regulations are invented but we already have those regulations. They're called the "Highway Code". Every regulation that a self driving car has to follow is printed right in that book, specific to each state and locality. Making a new law that says "that, but in a self driving car" is pointless. The law already exists. If it's being broken, it's being broken.
Yes, if a car is on the road and it's breaking the law, it should be removed from the road. But again, we already have laws that govern this. "But with a self driving car" isn't a special case. We've already written every law they need to follow.
People are killed from known issues with non-autonomous cars today, and companies are getting punished for them. There is already precedent. There are already laws. They exist.
