Instead of parking between 2 cars, can park beside 1. So you
only need to check 1 side. Usually for back parking, aims into the
slot first. When your car almost reach the slot, turn out and when
done nicely, your butt should be pointing toward the parking slot.
Remember, easiler to park your car like that, than aligning it
perpendicular to the parking slot.
Practice and note the position of your rear window with respect to
the parked car. So if you park too close or too far, the next time
you can change your alignment.
