The potential benefits of tilting, compared to the rigid alternative, include: The ability to balance the moment caused by lateral acceleration in a turn, due to high speed, tight radius, or both, with a counter moment caused by gravity, means these vehicles do not have to be low, wide, and/or slow.
Tilt-A-Whirl is a flat ride designed for commercial use at amusement parks, fairs, and carnivals. [1] The ride consists of a number of cars which rotate freely while moving in a circle. As the cars revolve, the floor of the ride undulates so that the cars rise and fall as the ride spins.

The pawl bears against the surface at an angle so that any backward motion will cause the pawl to jam against the surface and thus prevent any further backward motion. Since the backward travel distance is primarily a function of the compressibility of the high friction surface, this mechanism can result in significantly reduced backlash.

A Roman poet Lucretius, in 50 BC, said "Linen-awning, stretched, over mighty theatres, gives forth at times, a cracking roar, when much 'tis beaten about, betwixt the poles and cross-beams".
