Line Lock:
Explanation: Line lock is a feature in a car's braking system that allows the driver to lock the front brakes while leaving the rear brakes free. This is commonly used in drag racing to perform burnouts without having to use the parking brake or manually hold the brake pedal down. By locking the front brakes, the driver can spin the rear wheels while the car remains stationary.
