I assume you just pulled that out of thin air but even if you hadn't, it is completely meaningless. We have nothing to compare human performance against. Humans have been driving for more than a century. What are you going to compare that to?
As to how preventable accidents are- sure, if you remove factors like the ones you say, you'll reduce accidents, but humans suffer from those cognitive impairments on top of our extremely well-tuned cognitive apparatus. Computers have nothing of the sort. They may not get distracted, but they're rubbish at doing the thinking that keeps humans safe on the road the vast majority of the time (given that the vast majority of drivers don't get killed in accidents).
To put it plainly, if you put a brick on the gas pedal and lock the wheel, you'll reduce the amount of accidents caused by cogntivie impairments like inattention and poor judgement- but you won't reduce the overall rate of accidents.
In other words, if you hand control to a system that doesn't sleep on the wheel but can also not tell a puddle from a boulder, you will increase risks rather than reducing them.
