One of the Most Interesting Apps of 2011: Valeo's Park4U Remote Control App

Automotive equipment maker Valeo demonstrated an iPhone app at the 2011 International Motor Show in Frankfurt that will allow you to park your car.
The iPhone app doesn't allow you to steer your car. The remote control app allows you to only accelerate and brake, but it works in conjunction with Valeo's Park4U technology that can be found on cars from Lincoln, Ford, Audi, and Volkswagen, which uses sensors around the car and steering wheel control to automatically park cars into parallel and perpendicular parking spots
