A related thought: if autonomous cars always prioritize pedestrians, I wonder what will happen to downtown main streets? Will you still have to give way to cars crossing the road? Or will there be enough pedestrians that you could simply walk across the road at any point and the cars will be forced to wait?
The traffic lights around me are really annoying for pedestrians, you have to wait for ages. I'm happy just crossing on a red if there is no traffic. But maybe if every car is autonomous, I would just make cars wait for me?
