I would say that from what I have experienced in life is that those most susceptible to getting caught out are those looking for a quick buck, those who are in a tight spot and looking for a way to get out, and those with a lack of what I call 'street smarts'.
The only thing I got caught up in was a slam-on in which some **** **** slammed on his brakes on a slip road with no reason to other than the 'mystery ghost care who had broke in front of him then sped off'. luckily there was no damage and I took photos. The retard still tried to sue for 'whiplash' and apparently the 'huge crash' had damaged the 'inside workings' of the car. Luckily the pictures showed that the lack of damage and no deployment of airbags meant it was fraud and I won, but I would say always take pictures at an accident, apparently they can claim for up to 2 years, which some scammers do, knowing the victim would have forgotten by then.
Not trading related but legit advice anyway.
