This involves a mission that requires you to buy InterGlobal Films on Prawn Island. The mission is "G-spotlight" and has you do some motorcycle roof jumping (probably the most fun mission in the game).
First play through the mission going up the elevator to see what it should be like normally. Most likely you\'ll fall off a roof your first time through. On your 2nd trip to the elevator keep mashing the X button as you\'re waiting for it to open. Your bike keeps accelerating when the elevator doors shut, slamming you into the bystanders over and over and best of all you get to watch helplessly on the security camera.
If you wanna try something else on that mission, during your first big jump press R2 or L2 + O. This is shooting from your bike but since the first big jump is slo-mo it looks like an ah-nuld flick.
