Do third-party "autopilot" systems require ISO 26262 certification? I know that car manufacturers and tier-1s spend lots of time and money getting their safety-critical code certified. Do the same requirements not apply to aftermarket solutions?

Actually, now that I think about this more... does Tesla's autopilot have ISO 26262 certification? I hope that the recent advancements in self-driving cars isn't a result of tech companies bending or breaking the rules, but I don't know enough about when ISO 26262 is required (if at all).
