Self-driving cars are the natural extension of active safety and obviously something we should do.
Prudence is not hesitation, procrastination, or moderation. It is not driving in the middle of the road. It is not the way of ambivalence, indecision, or safety.
Faster roads are not always safer roads - and virtually all societies, democratic or authoritarian, prefer safety over speed, even if many of their citizens enjoy fast driving.
Have you ever noticed that anybody driving slower than you is an idiot, and anyone going faster than you is a maniac?
Safety is something that happens between your ears, not something you hold in your hands.
