Forget self driving, all they needed to do is build a reliable cool looking electric car with good software - all the difficult pieces apple already has tremendous expertise - battery and software. This is a complete failure at the leadership that they kept pursing level 4/5 self driving then software only then cars again... instead of just making a regular EV that is reliable and has good software (which no-one really has even today, except maybe tesla).
Tim Cook has spent all the innovations steve job built, all Tim did was ensure efficient operations and iterate on steve's products. The ONLY meaningful innovation that happened on his watch is apple silicon and that is largely derived from iPhone's A chips and by the chip design team.
Even as a business suit not a product guy, he failed to make decisive moves - such as acquiring disney, arms, ev/car company at their lows which would added tremendous value to apple, or innovate and become the leader in battery tech (instead of the chinese) or as an "operation expert" move some of the manufacturing such as screen panels in-house instead of paying samsung their biggest competitor to make them. He did nothing, instead, kept the cash pile in the bank/share buybacks, and bought bunch low risk small companies to play safe, no balls.
The only reason Tim Cook is viewed as successful is because of the strong product pipe line steve built before he died that Tim is able to iterate for the last 10+ years, and lack of serious competitor / innovation to disrupt those products. I think Steve really made a mistake putting an operations guy instead of a product guy as the CEO.
