If you are about to crash during a SuperTrick move, simply get to the nearest rail. You will continue the trick on the rail and still get points.
Go to Aerodome and grind on a rail. Hit all the targets, then go on to the rail above the lava. Hit the rail switch targets, then jump before you go onto the other rail. You should fall, but nothing will happen.
Note: A controller is required for this trick. Near the end where the big jump is, do your special trick then press R1, R2(2), R1, L1, L2(2), L1. The "Rated E For Everyone" sign should appear, but will not affect game play.
