5 -- Self-parking cars
Lexus' self-parking feature is optional on the LS sedan. Line up the superimposed square in the backup camera with your intended parking spot, then gently let off the brakes, and the LS will slowly steer around adjacent cars as it backs into the spot. You have to press the brakes to bring the car to a stop at the end. We didn't know Big Brother had a valet job, either.
