So if your car inexplicably fails to install a safety critical update, you get blamed? Because I'll bet that the software vendor will say it works just fine.
Just today we have had HP stuffing windows PCs because their images were wrong - and the blame was passed on from MS to HP and back and forth all while the users (me, I have one) had to do a workaround every time you rebooted.
I just don't have faith in this. Call me cynical but both car manufacturers and software vendors have previous in this. God help us when its both combined.
