What are the ethical and legal issues of self driving cars being released in the UK? What are the ethical and legal issues of self driving cars being released in the UK?

This question came up on our exam today and I was left in a daze.

I initially thought it would be issues like the legal driving age for self driving cars since they are AI do you need a minimum age limit?

Another one I thought was whether or not you need driving licenses for AI cars?

Could someone please list all the possible ethical and legal issues that surround AI controlled cars?

This should be enough to get you started.  (In terms of how it may apply in the UK, I leave that for you to determine;)
