Earlier quoted context omitted.
Tesla self-driving is better than a bad human driver. There are loads of bad human drivers on the road. Someone has to be liable, but I don't really care if it falls to Musk or a Musk simp. I do care if we kick yet another key technology out of the US only to have to rent it back years later when someone else picks up the torch. Let's not do that.
Can you be absolutely certain that self driving can deal safely with every possible road irregularities, obstacles, bad, incomplete, damaged or tampered road signs, and other unpredictable events? Self driving on public roads done right is damn hard; probably harder than sending a manned but completely automated spaceship to Mars and back.
