When I park a car, I usually go into the space head first. My husband
backs in. I'd rather back out into a big space than back into a small
space.

Backing a car into a parking stall is justified by the same physics that
indicate
a bow-first docking. :-) You keep the steering end where it has the most room
to
swing while you accurately position the pivot point into a confined space.

Leaving a parking stall front axle first gives a greater number of early
options to incorporate a useful angle to the departure.
When the front axle exits the parking stall last, the front (steering) end of
the vehicle is constricted by proximity to other cars.

One major difference between docking a boat and parking a car. On a boat, it's
perfectly acceptable to bounce off a few fenders.
