So, disregarding how the self-driving car decided who it is best to kill in any given situation
This old chestnut needs to die.
Rules for this already exist, it's just that human drivers dont follow them. An autonomous car will be programmed to take the course that causes the least damage and is the most legal. So they would choose a rear end crash over a right angle crash because a rear ender presents the lowest risk of casualties. If you think that veering out of your lane to avoid a rear end crash is a good idea, you completely fail at driving (first in failing to keep a safe distance, secondly in not having the time to check if it's safe to change lanes).
This is already sorted. They dont care that the person to the left is a meth addict and the person in front is a Nobel laureate, they'll take the path that presents the least risk. Beyond this, if the car is already in this situation the programming has failed.
If Google wants to sell autonomous cars, Google should be liable for anything the damned thing does.
So Colt and Armalite should be made responsible for mass shootings because they make guns?
I think firearm restrictions are sensible, but even I have to admit that the problem isn't the people who sell guns, it's the people who use them.
So once again, this is a legal problem that is already sorted. We already have extensive rules to determine who is at fault in an accident and they dont need to be changed for autonomous cars. When it comes down to it, if the driver cant be identified the onus comes back to the vehicles owner.
If you crash your car into a house and do a runner, you cant claim you weren't the driver because you weren't found at the scene. Unless you can nominate another driver who admits responsibility, it will be considered your fault (so be aware who you lend your car to). It will be the same with autonomous cars. For decades after their introduction you will still be required to pay attention to the roads, even though the car is choosing the actions you are still responsible for ensuring the car is doing its job properly and ready to take over if it fails. If it crashes whilst you were managing it, you will have failed your duty of care.
