After you have equipped your car (or SUV) with Hydraulics (Level 1, 2, or 3 will work) pull up to another vehicle or a wall and hold the R1 button and move your Left Analog Stick up and down in a rhythmic fashion to get your car rocking up and down (not bouncing). If you are close enough to the obstacle in front of you, your car will shoot straight up into the air, sometimes doing outrageous flips and spins. Once airbourne, release all the buttons, and if your car has soared into the sky parallel with the ground, "Hangtime" points will start to add up, sometimes 400+ Not very purposeful, but rather hilarious to watch. At the very least, you are refilling your nitrous/racebreaker. *Works in Online mode also*
