When I was taking my road test, the instructor told me to parallel park into a tight parking spot (well, tight according to abilities at the time).
I messed up with the parking, I was to close to the car in front and two close to the curb.
Knowing that touching the curb or the car would make me fail the test, I was at a loss.
So I started inching my way, one inch forward, turn the wheel, then one inch back. I repeated this for around 5 or ten minutes until I finally was parked.
I was sure that I failed, however the instructor said that there is no time limit and since I managed to park I passed the test!
