Neuro/orthopaedic or trauma surgery after you have been hit by a lorry ( perhaps driven by a European driver near or over his tacho limit) focusses the mind extremely well.Sorry if that sounds melodramatic but it happened to a friend of mine driving an MGB ( despite reflective number plates!)

We have two friends that had one back over them as they took an off ramp. The TIR was backing down the ramp because he had missed a turn into the lorry park. He didn't even feel the bump and it was only when one of them started banging on his door that he stopped (just before running over the one trapped underneath). They were on motorbikes and I don't think reflective plates were much help to them either. Fortunately no serious injuries but the two bikes were destroyed. Took 4 years to get the insurance payout.
Edit: despite one hell of a fright they are both still riding motorbikes.
