If this car insists that pedestrians go first, to the extent of stopping and projecting a sidewalk in front of them, it'll never go anywhere very fast. People will just step out into traffic trusting that the car will stop for them - and in areas of any significant pedestrian density that'll mean that you're constantly stopped or going at a couple of miles an hour. Without the prospect of getting run down and squished if you behave like a total moron, that's what people will do.
