Go to the part of the movie where Ferris notices that the odometer has high mileage...right before Cameron flips out and right after they pick the car up from the parking garage. Keep your eye on the car...when the camera switches views from the car to the odometer, the car magically switches a lane! Also keep an eye on the other cars next to them...for some strange reason, they don't pull up as far as he does when Ferris stops the car!
