You think Kalanick was pushed out because of the one self-driving crash, and not the sexual harassment scandals, theft of medical records, or threats to journalists?
(Of course it wasn't any of those - it was because the self-driving program wasn't anywhere close to working even ignoring all the safety problems. You can do all those things - the only thing you can't do is waste investor money.)
Travis autonomy would take a couple years. He spent some absurd sum acquiring the talent for ATG and gave them unrealistic deadlines. The program was a shit show. A pedestrian was killed, the program was stopped, Investor money was lost. While this is not the only factor leading to Kalanick's ousting, it was a big one.
