The Instant Handbrake powerup is an enhancement to the car's handbrake. Now, pressing the handbrake key will make the car lose all momentum, stopping instantly. It can also be used in mid-air, as it'll stop the player and keep them floating, even though the car slowly falls down. This powerup is useful when a wall approaches and there isn't enough time to brake, and recovering to safety can be a pain in the wallet. Pressing the handbrake key will make sure the player is stopped and unharmed.
