Well as for whiplash and claiming compensation for pain and suffering why not?
I just claimed again after another accident for my sore back/neck and shoulder etc after a muppet ran into the back of my stationary Mini Cooper at a roundabout being drivien by my pupil.
Other driver said "I was looking to the right" I said "I know where you wernt looking!!!!"
Anyway, I had reasonable amount of pain etc for nearly 2 weeks. Major inconvenience etc getting stuff sorted out and loss of some income. Why should his insurance company not pay? All he had to do was look where he was going and I would not have been sore etc.
I did not milk it, I was able to continue working but had to get out and walk about for 5 mins every hour etc. Had a reasonable discussion with his Insurers (Axxa, very good to deal with btw.) and its all settled. I'm happy there happy etc.
