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.
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.

Back-in angle parking along Council Street in Frederick, Maryland, USA Back-in angle parking in Chicago, Illinois, USA. Back-in angle parking, also called back-in diagonal parking, reverse angle parking, reverse diagonal parking, or (in the United Kingdom) reverse echelon parking, is a traffic engineering technique intended to improve the safety of on-street parking.
Typically, the vehicle will move backwards. However, when on certain vehicles the shift selector can be placed between the detented park and reverse gear positions; i.e. in false park the transmission is in hydraulic neutral, without the parking pawl engaged. As such the vehicle can also roll either forward or back in neutral.
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 ...
