Parallel parking is considered to be one of the most stressful and difficult skills for new drivers to learn.
Two major types of parallel parking technique differ in whether they will use two or three positions of the steering wheel while backing.
Less-confident drivers may choose to drive further while transitioning, making it a pronounced middle step of three.
Such a step allows greater tolerances to avoid hitting anything, but forces the car to start further from the road's edge and requires more space to the rear.
Beginning in the early 2000s, automobile manufacturers began providing computer assisted automatic parking software on some models that allowed drivers to engage the software to complete the parallel parking maneuver hands-free.
