i know its not much cop now, but something i am going to bear in mind if it ever happens to me and its an incident like you had, i am going to use my camera phone to get pics at the scene, maybe even get them to pose in it, it may be of use later down the line!!
feel for you mate, jen did something similiar about 6 years ago at a roundabout, went into the back of a volvo that had moved off then stopped.
got a letter through 9 months after the incident she had been off work since the accident, had had to have accupuncture, was suffering reoccuring nightmares and was scared to drive again!!
damage to our astra? 400 quid
now that pissed me off!!
