> Putting cameras into cars requires processors, ram, all manner of chips and compnents that a car didnt need before.

Was there a single mass market consumer car sold in the United States in this millennium that didn’t already have processors and RAM in them?

I would be absolutely shocked if there was a single car for which the relatively recent backup camera requirement required them to introduce processors and RAM for the first time.

I’m pretty sure that you can buy aftermarket backup cameras. The car can be a dumb bunny, and still have a good camera.

Yeah, my 2005 beater has both CarPlay and a backup camera. Cost me $40 and an hour of labor.

I believe that in some vehicles the backup camera actually runs on a separate (possibly real time, otherwise certainly heavily nice'ed) system. Tesla has a recall where they had to nice the backup camera software. The problem was if the display freezes or is delayed, then the driver is backing up and not aware that he doesn't see where he is going (he thinks that what he sees is representative of the area around the car currently).

In Hyundai and Renault I've seen it first hand that it's a separate subsystem that works even when the infotainment is dead/unresponsive/glitchy (it's like that probably everywhere, these two are just the sample I have).
