You need a software first agile mentality from the leadership of the company on downwards and these legacy companies just dont have it.
It's been an absolute disaster, with billions of dollars spent to produce delayed, buggy software.
Agile workflow for frequently updating non-critical software in devices that happen to be cars? Sure.
The problem with software companies is they’re bad at hardware for the same reason.
User experience companies can be good at both. Maybe not as good at hardware as a hardware company, maybe not as good at software as software companies.
Apple’s the obvious example, but Google, Garmin, heck even Starbucks are also good examples. Start with the user experience, build hardware of software or whatever else is needed. Specializing in a tool has value, but limits you to that tool.
I can release a website with a list of known bugs. Do any govt allow release of cars with known bugs?
Safety-critical firmware is scrutinized fairly well (not because it's not a side project, but because of regulatory constraints combined with the small scope allowing the car manufacturers to treat it as a fungible good), but other software is not, even broken feedback loops interacting with that firmware.
If I could walk everywhere the rest of my life, I would.
