From an ISO 26262 perspective, it seems like for the driving scenario of "unexpected windshield wiper speed increase", they may have set the controllability to C0 (Controllable in general) [1] when it may have needed to have been something less controllable (C1 means 99% of drivers can avoid harm in the condition, C2 means 95%, C3 means less than 90%). That probably set their risk level to something lower than it actually was. They probably need to do some tests for anything they're diverting to the touchscreen to figure out how many drivers can manage the situation within the time frame of avoiding a crash.

It looks like Tesla's job postings reference ISO 26262 experience as a plus [2], but I can't get a straight answer to Tesla's adherence to it in-house. My understanding is that no government mandates its use, but lots of car companies adopt it anyway.
