When you buy semiconductors on digikey or whatever, there are several different 'classes' of performance. Everyone imagines milspec being the top one, and it's true, but for most people the ideal class is 'automotive'... Because precisely of what the parent said: tolerances of temperatures to 140F or more. Think of a car sitting in a baking parking lot in Phoenix, no shade. You don't build semiconductors for that purpose by using 10nm process then adding a lot more redundancies when all you need is a simple opamp. You instead build the thing beefy and resistant to the environment. And all the excitement over new chip plants by TSMC etc, won't do a thing for these automotive applications.
