A scooter's Turn-around Width is the minimum distance between two parallel walls (such as a corridor) needed to be able to turn the scooter around, using a multi-point turn manoeuvre, such as a 3 point turn but not limited to 3 points. This is provided as a practical measure of whether a scooter can be turned in a given space.
A scooter's Turning Circle is the Diameter of the circle drawn by the outside edge of the scooter when turning it around on full lock.
A scooter's Turning Radius is simply half of the Diameter measure described above.
