Restarting from a full stop requires good pedestrian awareness. Cars that accelerate automatically from a stop already have the radar/ultrasonic sensors necessary for collision avoidance. So they should never accelerate into a pedestrian (and not allow you to, either!). If anything, collision avoidance systems have better pedestrian/cyclist awareness than human drivers do, since they can "see" objects in blind spots, etc.
