When lives are involved handling edge cases is everything. The person stepping off a curb, the cyclist that falls in front of you, the car that weaves in its own lane and can't be used as a reference, traffic lights that are out of order, stop signs hidden by trees... and on and on. Mess one of these up while autonomous and severely injure someone and you're done.

Human drivers might only see one of these cases a month, or 6 months, but not driving over someone in that case is what is critical. Not saying it's an impossible task, but IMO it will require a lot more training data than humanly possible for one person to generate.
