Even with open source, I'd be doubtful (and concerned) were that an option. There's no reason you can't have open source code (available for public scrutiny/liability purposes), but require that on-road, cars require a particular signed variant. Sort of the anti-GPL3. Some sort of public bugtracker/remote update mechanism (again, given suitably authenticated binaries) would also be nice. Actually, it occurs to me from watching far too much Top-Gear, that a fair number of high-end cars have a "Sport" button that does all sorts of things to your ECU, brakes/suspension/steering controls, and (afaik) is strictly speaking only legal for off-public-road/private racetrack usage. Having something similar (and with a log of entry/exit times into each mode for use in crash investigation)[1] might make it possible to experiment. Still strikes me as pretty scary though.
