Ah, so it is working now?
I'm not exactly faking the impact - when the bike hits something tokamak bodies are created for the bike and for each part of the rider. The rider's parts are jointed together correctly. Tokamak bodies are also created for the traffic vehicles.
I am then setting these bodies to the correct velocities before the impacts and then the simulation is left to get on with it.
So when the crash starts the rider is in the correct position on the bike. Obviously the bike tokamak body is not completely bike shaped, just a cube and a sphere, but it seems to work.
