The stunt performer in the fast attack vehicle pulls alongside the performer driving the motorcycle and transfers from the vehicle to the motorcycle. The motorcycle drags the stunt performer and then the driver on the motorcycle maneuvers the bike so the performer being dragged swings into a palm tree. This was all done practical. The stunt performer was wearing a harness with an overhead traveler rig to help him flair out as the bike came in and made the turn to miss the tree. A Deadman cable with a bit of deceleration in it was added and with the correct length the stunt player would just touch the tree and wrap his body around it as if he slammed it hard. The hit on the end of the cable was hard and was at a dead stop at 20 mph. CGI painted out the wires.
