Yes, in this particular case, maybe the car should have moved a bit. I'm talking about the general case. What are the odds that a car happens to come to a stop with its wheel exactly on top of someone's limb, versus having that wheel finish up somewhere near the person where further movement might cause additional harm? And how can the car know which situation it's currently in?
