He's not talking about ECU firmware, he's talking about infotainment software. You can't use the best practices for ECU firmware development as you use for other types of software development: it would never get done! Safety-critical software running on bare-metal or an RTOS (like for ECUs, ABS controllers, avionics, etc.) isn't much like software for doing GPS mapping and other infotainment functions, and the development process is entirely different. The latter has orders of magnitude more lines of code and is far simpler in scope. The OP is right; currently, automakers basically outsource all their infotainment software, and generally do a poor job with it, though it's getting better. Considering how much drivers now interact with these or similar systems (usually on their phones), to do things like stream music and especially navigate, automakers should be doing a better job integrating this stuff into the cockpits for ease of use and safety.
