The minor bump and the idiot trying to claim compensation.

So after an evening shift at work just over 2 weeks ago, I had a very small bump with another guy finishing work from the store next door. As I was pulling out, I'm sure I looked left and right, it's so natural you don't even think about it and the next thing I knew I saw a blur of blue and heard a thud. We both pulled over and got out. He said that it was alright because there wasn't even any damage, and I stupidly pointed out what I saw and asked "What about that?"... We exchanged details and he said that it was so small that his dad should be able to just sort it out.  
 
A couple weeks go by and I don't hear anything so assume that he didn't put in a claim. I then get an email from my insurance saying that he has taken out a claim for his car and a personal injury claim for whiplash. I rang him to ask if we can just sort it out between us, since the excess I would have to pay would be 10x the cost of just fixing the tiny bump. But no, he can't back out now, because he's hired a solicitor... 
 
I'm fed up of people these days always trying to make a quick buck through injury lawyers. Like you can get whiplash from a low speed bump in a car park. 
 
Someone reversed into my car in a car park once, the damage was worse than the damage I caused to this guys car and I didn't bother claiming. Maybe I should have.. 
 
Anyone else had any minor or major accidents on the roads?
