It seems unlikely that we will have fully self-driving cars soon
Maybe not from Tesla, but Mercedes already sells 2 cars which have limited Level 3 self driving functionality. Up to 50 mph you are legally allowed to divert your attention from the road and do something else, you just need to be ready to take back control within 10 seconds of the car telling you to do so. Mercedes is so confident in that system that they are taking legal liability for any crashes caused while the car is in self driving mode. And Mercedes is already planning to get the car certified for speeds up to 75mph soon, so it will be usable at regular highway speeds
Well, so far these cars have driven a lot of miles without crashes. They don't need to be perfect, they just need to be better than a human driver, which is not a very high bar to set
