When you learn to drive, that reverse-parking thing seems so difficult.
Part of the reason is that the steering wheel’s connection to the wheels is geared. It’s hard to sense, especially when going slowly, where the wheels are actually pointing.
Today’s invention is a mobile app which sits on the dashboard above the steering wheel and shows a learner exactly where the wheels are pointing.
(It does this by using the mobile device’s camera to read the position of a circular barcode attached to the back face of the steering wheel and then entering the make of vehicle for calibration).
