>Anything less than 100% FULL automation is MORE dangerous than manual driving, because the "driver" will almost certainly lack any situational awareness.

Something I worry about is that if SD became normal, then people would never get the experience of thousands of hours of driving a car in countless situations that is needed to develop good judgement, much less quick reflexes. And so when a rare situation arises when they need to take over, they won't be able to do it well.
