The new formula is the result of collaboration between Vauxhall Motors and maths professor Simon Blackburn, reports The Daily Express.
According to the expert, a driver simply has to gauge the radius of his/her car's turning circle and the distance between the vehicle's front and back wheels.
Then, using the length of the car's nose and the width of an adjacent car, the formula can tell exactly how big a space needs to be for your car to fit.
The boffin says by applying this to basic parking guidelines you can work out exactly when to turn the steering wheel to slide in perfectly.
