I still tend to think the 360 cameras would be the first step, to expand capability while still in semi-autonomous operation.
No car currently in operation has redundant steering equipment or fail-proof computers for any aspect of operation that I'm aware of, and the only car with any sort of redundant power train is the dual motor Model S/X - and even then it is only for certain failures of the front motor only.
I think Elon may be setting an excessive standard considering the state of the industry - but if he can manage it at a reasonable price I won't complain.
I agree. I also think that they're taking it one step at a time and dual cameras should allow for use of autopilot through intersections -- a lot sooner than other redundancy requirements -- hopefully.
