I am not a car. The way I am facing is not necessarily the same way I am moving (not striclty the case for cars either, but that leaves parts of the tires on the road). For example, for multiple flights of stairs, where the path would suggest repeated 180 degree turns in the same direction, I like to replace every second one with a turn in the other direction combined with some sideways movement component.
