Plot hole: When Bond uses the laser on his Aston Martin to cut the police car in half, the laser supposedly cut all the way through the length of the bottom part of the car. If that's true, the brake lines would have also been cut. The top half of the car slides off when the driver applies the brakes. If the laser cut clean enough for the top half to slide off, then the brake lines were indeed cut by the laser. How could the driver apply the brakes if the brake lines were cut?
