Yes they usually have very strict rules and requirements to do deep testing.
I honestly don't know how that Boeing debacle escaped through Functional Safety standards at the company.
In car industry also topics like Functional Safety are taken very seriously.
For ASIL-D which is highest safety standard, you need to make sure there is redundancy in system. Brakes, and autonomous driving would be classified as ASIL-D relevant functions. Such system for example need two independent power supplies for control unit in case one fails then the unit will not stop suddenly exposing the driver to danger. There is also special safety SoC on such control units which monitors other function on this control unit.
I work im Automotive industry at one of larger suppliers therefore I know a few things about this industry.
What I can say is that control units are getting very complex in the recent years increasing testing efforts.
What makes me wonder though with this press release from Tesla is if AMD has now automotive grade components.
The cars are expoxed to many harsh environments and usually we don't use consumer grade components there.
The component suppliers need to make sure certain temperature/humudity/life spam criteria are fulfilled.
Unlike consumer products the car components need to survive in tough environment for longer time.
I as car owner would be angry if I need to replace parts after 3 to 4 years for example.
