Having worked in self driving cars safety, the process there was simple: get confidence in SIM (integration tests for safety scenarios), validate in the test bed, approve features for maturity, then when released in the public for testing, do a trial exposure to the real world and recall if something is off.
A lot of these companies have gone the way of Tesla and decided to just patch on top when the fix is out and hope for the best, which is irresponsible.
We need the regulators to treat this as self driving cars.
