this is for parallel on left
1.move up alongside the front car and stop when you're slightly in
front.
2.start reversing slowly, when the back of your car is in line with
the back of the front car, achieve full left lock quickly while
still reversing slowly.
3.when your left side mirror is parallel with the back of the front
car, turn to get full right lock while keeping your car on the
move...if you dry steer, you'll end up too far out. how fast you
turn the wheel will depend on how much more u need to move
in...practice makes perfect
4. when you're in position, straighten the wheel and do any minor
adjustments
