> Humans can write very good software. The Space Shuttle engineering group wrote some damned fine software. They look literally nothing like the #YOLO coding that makes up most of Silicon Valley, and deal with a far, far more constrained environment as well than a typical public road. Safety-critical software like that used in the space shuttle is incredible expensive for the level of complexity involved (which is not very high, compared to other projects). A self-driving car is probably one of the most complex software projects ever attempted. If you were to apply the same techniques as the shuttle to achieve self-driving you would literally never finish (not even the tech giants have enough money to do this). So to achieve this you not only need to solve the very difficult initial problems you also need to come up with a way of getting extreme reliability in a much more efficient way than anyone has achieved before.
