The human accident rate is about one per 500K miles, so if they were able to get in that range, then yes, they would have succeeded; drivers would be able to stop paying attention to the road without putting themselves and others in danger.
But the current FSD beta's intervention rate is more like one per 10 miles, judging from some quick googling. I see no particular reason to assume that incremental improvement can take us from 10 to 500K.
