The trouble with self driving cars is that in the UK we have roads that used to be cart tracks. A simple example: https://firstname.lastname@example.org,-2.7731751,3a,75y,94.96h,75.31t/data=!3m6!1e1!3m4!1su0SxldD9HLLhhzwjDxhA_Q!2e0!7i13312!8i6656.
Bit of grass in the middle of the road, single lane, blind corner, hedges and trees.
What happens when a self-driving car meets a meat bag? Is it going to crawl along? How is to going to agree who can do what? Are these roads off-bounds? So, do all future cars need at least some method of 'switching back to manual'?
