Open Source car software? I’m all for it. Well, with some caveats. I don’t think current car software should be open-sourced, since it’s probably full of security holes. Future car software should be, I think. But only if for the first year it is tested by the executives of the car companies in their own cars. If they survive attempts of black hats to take control of their cars and drive them into trees and off bridges, they can sell cars with the code in them. If they don’t, karma.
