Google had worked on self driving cars on a while, the problem was probably the hardware was not ready. Tesla AI takes too many risks in my opinion because it is missing important sensors(IMHO) it crashes often with big trucks or buses proving the optimization they do are not safe enough and I prefer a company that is not risking my life by selling me a driver assistant that is not that good and is badly named autopilot.

I have a feeling but I can be wrong that you think Tesla innovated the AI on self driving cars and GM or others are profiting for it, self driving AI was studied and worked on before Tesla, Tesla are in the group of companies that risk the life of others where others waited for the tech to be better. Also other companies like GM already had driving assist functions, they now upgrade them with new features
