This should be in the 'grouse' section! Within a couple of years of buying my (then) new 156 Sele S/W, I had had all four corners scraped by others in my work car park (none reported to me, but being a hospice = lovely nurses = can't complain!) Why don't people realise that a steering wheel turns more than a quarter turn?
But supermarket car parks are worse. Within 6 months of purchase, I had parked in Tesco's for 10 minutes to buy a card, and when I came out, found that my car had been ring-gouged on every window and every panel on one side, including rear and bonnet. Being parked next to a Tesco 'no responsibility' sign, I stopped a passing police car instead, but they merely said 'Hard luck - it's kids. You parked too close to the direct route from the shop into the housing estate'! I didn't see a warning sign for that! And still got an 'own fault' bad mark on my insurance.
