Practical in that we get to have widespread self driving cars. Real ones where you can look away from the road.

Do you have an "offending activity" in mind? The existence of car accidents isn't one. If you want the manufacturer to be liable for every mistake the car does, that's fine. But since that will increase the price of self-driving, likely as a subscription, it basically resolves into a type of insurance.

If the self-driving designers perform actual wrongdoing, that's a separate issue that can be handled like any other recallable hazard.
