four wheel 90degree rotation mechanism and car parking easily

It gives immense pleasure when a person rides a car and goes on a smooth nice highway. On the other hand, the same person gets frustrated when he has to make sharp maneuvers to parallel park his car in closely packed parking spot with front and rear car taking a portion of his parking space. I suggest a feature in cars that may alleviate the pain. Let’s see the pain and the solution.

Parallel Parking

Parking on the streets, in apartment complexes and even some other parking areas, requires one to Parallel Park a car. In Parallel parking of car, a person needs to park his car lengthwise parallel to curb. There may be car ahead and behind the parking spot where this car needs to be parked. The space provided to park this car may be around 1.5 car length – 1 length for the car and 1/4 length ahead of and 1/4 length behind the car.

Method

The recommended and easy way for parallel parking of a car is

Stop the car parallel to the car in front
Turn steering wheel towards the curb and move the car backwards (reverse gear)
when car has entered around 80% length in the parking spot, turn steering wheel away from the curb and continue moving
Watch for the car in the back and the curb on side
Straighten the steering wheel and move the car to maintain equal distance from car in front and back
Drawback of parallel parking in conventional way

Parallel parking a car is a skill that one needs to learn and practice. One may not perform parallel parking without first learning it. This is the reason, Department of Motor Vehicles in USA (http://en.wikipediawiki/Department_of_Motor_Vehicles DMV on Wikipedia) requires a driving license aspirant to demonstrate how to parallel park a car.
Even with all the learning drivers do make some mistake while parallel parking a car and the result is nicks on the bumper of car.
Most of the time, parallel parking requires one vehicle to acquire 1.5 to 2 car parking length so that the car can get in the parking spot and come out of it.
Parallel parking requires a vehicle to move forward and then reverse causing it to travel more distance than was really required.
More distance leads to more fuel consumption
More distance leads to more wear and tear of the car
More distance and parallel parking causes more time spent
