I'd argue that the majority of victims are the result of humans suppressing their judgment. E.g. not because a human was incapable to drive safely, but purposedly chose to drive unsafely: overtake where it is limited visibility, speeding when conditions do not allow for it.

Attention-related crashes are likely a good chunk as well.

Also unsafe lefts and ran/stale lights. That's probably most all of them between our comments.
