If you write code that powers an EV's 'self driving mode' - which makes calculated choices, sell it and deploy it, when that car gets into an accident under 'self driving mode', you may not be liable (depending on the case and jurisdiction - as proven in the past). The driver is.

There are many instances (where I am from, at least - and I believe in the USA), where 'accidents' happen and individuals are found not guilty. As long as you can prove that it wasn't due to negligence. Could "don't be an asshole" as instructions be enough in some arenas to prove they aren't negligent? I believe so.
