Human drivers can already get information about that sort of problem, e.g. by using Waze. This requires that a human who uses the app has reported a hazard (the act of which could sometimes result in distracted driving), however, I would expect autonomous cars to tell each other about such things in the future.
True, but seeing as the article was about the ability of people to modify their car to for instance not do that I see where there could be a dilemma here.
They're pretty much one and the same, how can you allow someone to repair something without allowing them to modify it as well? What if they repair it badly?
At least, they will if we don't screw it up.
