When you click on the ‘Start’ button on maps, the map auto-rotates according to the direction of movement. But how is ‘direction’ estimated? Is it vehicle heading, cartesian coordinates, or something else?

Your phone would not know vehicle heading. It only knows your location and location history. If you had not been driving yet, it assumes that the map heading is toward the correct path. So if you are in a driveway, for example, it assumes your path is toward the road. You are the one to figure out to use reverse or drive. If you manage to change location at driving speed in the opposite direction of the assumed heading, the map re-orients to match.
