Having driven my son to his football game in our neck of Suburbia, I forgot to close my car door, leaving it not merely unlocked, but wide open. The double-beep of my alarm confused me somewhat when I pressed the remote, but I thought nothing of it, and went off with my kids to the pitch 200 metres further on.
Inside the car, albeit in the glove compartment, were my sat-nav and expensive digital SLR camera.
An hour later, the game was over and I ran back to grab my camera for a team photo. Seeing the open driver's door, I initially panicked, but was soon amazed to discover that nothing had been touched and everything was still in its place.
Try a stunt like that pretty much anywhere in Europe, and you wouldn't have had a car to come back to, let alone any valuable contents!
