Pull into a tight spot on the street without bumping anyone's bumper.
Align your side mirror with theirs, leaving about 2 feet of space between your cars.
Start backing up once your rear bumper is even with the other car's rear bumper.
A good checkpoint: your front bumper should be roughly even with the other car's rear bumper.
Watch your front corner — it swings out. Make sure it clears the car in front of you.
Aim for 6-12 inches from the curb and roughly equal space between the cars in front and behind you.
