The other solution is to make it trivial to both fix and detect errors, by using the same pinout so nothing gets damaged, and letting the computer tell you if everything is right. But with a car that's not really practical as things may not be accessible and easy to swap around. |

I didn't spend a ton of time at the plant, but there was one notable visit where I got to camp out at the station where, for the first time, a 12-volt power supply alongside the assembly line would be temporarily patched into the half-completed vehicle. This allowed all the modules that'd been added so far, to boot up and do some self-checks. There were certain missing sensors and communication errors that were expected at that point and would be ignored, but plenty of errors that _would_ be raised so they could be fixed while they were still easy-ish to reach, before the seats and trim panels started going in.
