For many people, parking your car in reverse especially in parallel parking instances can be a drag. True enough, it is indeed hard especially if you have no one to guide you on your rear. Using your side view mirror is a big mistake as your entire rear may be in jeopardy of hitting another car or post if you are not careful. In short, it is about making sure you make the right calculations as far as unseen distances.
Normally, it takes practice. You have to put proper allowance to be able to fit in. One thing you should note, do not be in a hurry. The more you rush it, the longer it will take for you to park properly.
The key here is to start at a diagonal approach, going in at perhaps the middle of the parking space. When backing up, slightly tile the steering wheel starting from the opposite direction and gradually towards the side where you will be parking. Even the pros cannot get it with one stroke so be patient. It’s all a matter of patience and proper spacing.
Don’t be afraid to hit the gutter as far as your wheels are concerned. Rather than denting your bumper, that would be better. If you do hit the gutter, forward your car slowly and then try to back up again with slight tilts on your steering wheel.
Always be alert as far as distance on the back car is concerned. Also, look at the car in front of you. It is all a matter of proper calculation. After some time you will be surprised you can drive in parallel parking like a pro!
