> I’m curious if automotive systems used more generic controllers for cabin systems if shortages like this would be less or more severe.
that wouldn't help. generic and not-generic controllers would still use ICs, and ICs are still what we're slowed down on. a more generic design might have to use more (or more complicated) ICs as well, to have more tolerant inputs.
more generic/standardized controllers might help if there were limits on printed circuit board manufacturing, or board assembly capacity. (as those things get cheaper/easier/faster the more identical units you make. and yes, that applies to ICs as well, but all of the widely used microcontrollers / jellybean parts are already produced in huge volumes.)
