Potholes!
Wintertime is when more potholes appear and existing holes get worse. These nasty road features not only give you a shaky ride but also knock your wheels out of alignment. Your suspension will wear faster and tyre life will be shortened, costing you yet more to run your car.
Now you, the motorist can fight back! A new campaign was recently started to raise awareness of the poor state of the UK's roads and get something done about potholes - see http://www.potholes.co.uk. Here you can see a map of existing potholes, report problems you find and get advice on how to make claims.
