A month or two after a visit to Iceland (my favorite country by far by the way), I received a ticket in the mail for speeding. It included a picture of the car I rented and a closeup of the driver's face- a face that did not belong to me (presumably another renter).

Luckily, a quick phone call and a copy of my drivers license cleared things up, but systems like these inevitably lead to "guilty until proven innocent" scenarios instead of "innocent until proven guilty".
