Parking is a skill and like any skill, you need to master it before you should be confident and brag about it. However, this is a skill that you would need if you want to own a car since you would need to do it every time you go out.
Drive your car off-road and look for the parking space. Maneuver your way through the parking space as you won't be the only one that would be parking your car. Try not to hit anything while driving. Carefully park your car at the parking space. The game gets harder and harder as you make some progress.
