Here we go again. You say one thing and someone responds pretending you are going to the extreme of that argument. This trick is usually done by only selectively quoting which you've done.
In the rest of my post (which you have cut from your response) I clearly said it's fine for people to claim what they SHOULD do, my problem is the "I'll get them back by claiming for as much as I can get from their insurance company" attitude which you seem to be advocating with the "wipe the smile off the mother's face" line.
OP should get his bike repaired sure and any costs he's suffered through being in hospital. But that's pretty much it.
The companies you advise he uses will be after compo for 'stress', compo for 'whiplash', compo for X, Y and Z too.
I was involved in a avery minor accident years ago, car on car which just dislodged the guy's bumper slightly. I spoke to him the next day and said I'd pay in full for the repair to his bumper and he refused and wanted to 'go through the insurance route' and I wonder why that was.
