Scary. You can't just floor it and get out of there when someone threatens you. Same would apply for other imminent dangers like floods or fires. When the car decides to stop, there's nothing you can do except wait for it to change its mind or run away on foot.

On the other hand, we can hope that self-driving cars make streets safer for pedestrians and protesters by obeying speed limits, always watching the road, and never driving aggressively/threateningly even when antagonized.
