Its amazing how you still see people get a rush of blood to the head and do silly things. I recently saw a guy lose his campertrailer in front of me - I could see it wobble and then lo and behold it came off and separated from the car. Luckily was only going slow so could avoid it - it ran into the gutter and a parked car. When I talked to him about it - he admitted he hadn't chained it up "because he was just taking it to the servo to put air in his tyres"!
