Wheel flop refers to steering behavior in which a bicycle or motorcycle tends to turn more than expected due to the front wheel "flopping" over when the handlebars are rotated. Wheel flop is caused by the lowering of the front end of a bicycle or motorcycle as the handlebars are rotated away from the "straight ahead" position.
Note the angle of the front wheels where blue indicates right steer, red left steer. Powerslide simulated using MSC Adams Opposite lock , also commonly known as countersteer , [ 1 ] is a colloquial term used to mean the steering associated with the deliberate use of oversteer to turn a vehicle rapidly without losing momentum .
Simple approximation for designing Ackermann geometry. A simple approximation to perfect Ackermann steering geometry may be generated by moving the steering pivot points [clarification needed] inward so as to lie on a line drawn between the steering kingpins, which is the pivot point, and the centre of the rear axle.

The combination of these two opposite torques creates a resulting yaw torque on the front wheel, and its direction is a function of the side-slip angle of the tire, the angle between the actual path of the tire and the direction it is pointing, and the camber angle of the tire (the angle that the tire leans from the vertical).

Cross sections incorporating a minimum of two through-traffic lanes for each direction of travel, with a typical width of 3.50 to 3.75 m (11 ft 6 in to 12 ft 4 in) each, separated by a central median. An obstacle-free zone varying from 4.5 to 10 m (15 to 33 ft), or alternatively installation of appropriate vehicle restraint systems.
A Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction. It is sometimes called the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon (1923–2008), [ 1 ] who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United ...
Two major types of parallel parking technique differ in whether they will use two or three positions of the steering wheel while backing. A skilled driver is theoretically able to parallel park by having their car move along two arcs, the first having its center on the parking side of the car and the second having its center on the other side.
The parallel parking problem is a motion planning problem in control theory and mechanics to determine the path a car must take to parallel park into a parking space. The front wheels of a car are permitted to turn, but the rear wheels must stay aligned.
