On Joyride, go to the ramp (not the broken highway). Jump off the ramp and turn around. Go towards the side of the ramp and
go to the first line that appears on the ramp. Slowly ride up to it and right when you hit it will send you flying. While in the air
you can do three backflips with three twists if you press and hold L1 or R1 and Up or Down.

Alternatively, go to the first ramp (not the broken highway) and gain as much speed as possible. Once you're on the ramp, pull
off on the side with the black line. This takes practice, but if you get it right you'll sail over the bouys and can drive around
outside.
