Pipe

A part of a pipe. The driver is piping.

Apart from being one of the internal levels, pipe is a special type of level or an area of a level whose width is smaller than driver's height. In order to pass a pipe the player has to go to a special position. This is done by putting the other wheel on the other side of the pipe and riding in a 90° angle compared to normal position (see the picture).

Piping (driving through a pipe) is not easy for beginners since the player needs to use turn and rotation keys really carefully to stay alive. The narrower the pipe, the harder it is to drive through it. The minimum width of a pipe is the same as wheel's diameter, but in that case, piping is very hard. The optimal pipe width is usually roughly two to three wheel's diameters.
