When delivering a bike and Cass and his gang appear, they will try to knock you 
off your bike by swerving in front of you. This causes you to wipe out, losing 
200 style points and a large amount of your bike's health. To avoid losing style 
points, wiping out, and damaging your chopper, press R (the front brake). Cass 
or one of his friends will hit you, but they will fall off their bike and you 
will receive 150 style points.
