Dodgy whiplash claims and spiraling car insurance costs. Here in the UK it has got out of hand, with insurance companies selling information to solicitors, who then try and convince people to make a claim, with this no win no fee culture.
The end result, everyone (apart from insurers and solicitors) loses as premiums keep increasing.
Be interesting to see if this is a worldwide epidemic, or is it a UK/US one?
Apparently even staged crashes are on the rise, so people can fake whiplash claims

At least in the UK it's been flagged by MP's, so maybe something will finally happen?
