The thing idn't that clear-cut in the COGS vs NRE area. From what I've seen, the firmware for each car model is VERY customized and for each generation they're solving the same problems all over again. At one time I was writing some firmware and it was very fun, but it felt sort of pointless, since I'm sure someone else should have already solved that problem at least once in the past in the same company. So they keep reinventing the wheel, with each product, with each car. It was very educational for me, but I'd love that once something is good, let's build on it... make it better, expand it. It could use from more transparency or some (internal, in the least) transition to a kind of opensource model within the company, where the good code survives and evolves and the bad one gets left behind...
