I think self-driving cars might be one of the hardest domains ever, considering they need to do the right thing (or at least avoid doing the wrong thing) 99.99% of the time to be even considered viable.

An AI artist can get away with a 5% success rate and still be considered viable for replacing humans.

Likewise, and AI programmer can be right only 50% of the time with expert oversight (someone sitting there fixing the code), or 90% with non-expert oversight.
