Troublesome analogy there. Dogs don't go on auto-pilot, you should always be in control of them. A better one would be, if your washing machine had a factory fault and wobbled out the door on a spin cycle and mugged your neighbour, Hotpoint would be paying out, not you.
It would make Elon liable for the Tesla that just crashed into you, as the driver can’t be held to have caused the collision, surely?
