There are some right scumbags when it comes to claims.
I had a small bump (at fault) in a petrol station couple of years ago, it was literally a 2mph bump. I was behind a guy pulling out, he went then changed his mind and slammed on, i went into back of him.
Was a young lad on his own, but i got a court letter through few weeks later telling me he was claiming a few grand for injuries to himself and two imaginery kids that were apparently in the back seat.
Luckily my insurance covered my costs, but i was a bit worried as it said i could be personally liable for his injuries etc.. but he got a nice big wedge for not a lot.
Hope you recover well mate, try too look at it positively, maybe this is the time to set on a full time employee and push on?
