Diagonal parking is preferred.
If you leave a dent, wait for a car, which is painted the same color as yours, to drive down the aisle looking for a place to park. The same rules applies to picking-up and discharging passengers. If the vehicle in front of you stops to let a pedestrian cross or another vehicle turn, pull into the lane of opposite traffic and attempt to pass him. When driving through a parking lot with alternating one-way aisles and angled parking spots, drive the wrong way. Then when you see a parking space, take 20 minutes to do a 12-point turn to pull into it.
