That's not a low bar at all. A lot of activities people do while driving are way more dangerous that driving "drunk". In fact, "drunk" (0.08 BAC) driving is often the baseline multiple that such activities are reported in.
Self-driving cars which are merely as safe as driving with a 0.08BAC will still greatly reduce traffic accidents. Of course, no one will report it as such. Having something that's paying attention 100% of the time is going to be a huge boon for traffic safety. Spending 15 seconds picking a song on your phone is all it takes to rear end a car or blow through an intersection.
