My mentality might be shaped by the fact that the last accident I was in was a pretty serious one - a drink driver hit me while I was on a motorcycle and sent me flying, and the surgery and recovery were absolutely fucking brutal. And it's actually a big part of why I was less active on here for about 7 or 8 months a few years back.
But I went after that fucker for everything - and what his insurance couldn't cover, I went after his personal assets, which is a bit shit for his family... but this cunt's already fucked over his family because he was arrested for drink driving after my accident. And it was his third fucking time being caught drink driving, which gives you a prison sentence here. The entire process was such an ordeal, though. From being in hospital, to having to make shitloads of doctor visits, to having to get a lawyer and showing up in court.
Here, as long as my neck's feeling alright... I don't see the need to claim it and potentially fuck this guy over when right now I'm feeling alright and it looks like things are going to be taken care of pretty rapidly. Granted, if my neck and back start hurting that changes things entirely. But this is an older disabled man, who apologised to me profusely - and accepted full liability while he was on a call with his insurance (which he fucking should, considering I braked to avoid hitting the car in front of me and he didn't). So I'd feel a bit bad claiming whiplash if I don't need to. Don't get me wrong, I think he's an idiot... but I just don't want to fuck over what appears to be just a poor old disabled man.
But your story's a bit shit, mate. What an arsehole acting like a nice guy and then claiming whiplash when he was fucking fine - hearing that kind of shite definitely makes me resent all of the dickheads on the road.
