Seatbelts

Conspiracy theorists always like to to refer to the thing where Diana Spencer is alleged to have told one of her friends, not too long before her unfortunate death, that she was worried that someone would tamper with the brakes of her car.

So why not, on the high-speed chase through Paris, do what I tell my kids to do. Pop on the seatbelt? It worked for the bodyguard.

Also on seatbelts, I read recently that when they ask drivers in the US why they don't wear seatbelts, the most common reason (beating even that it's a communist conspiracy or something) is that they don't want to be trapped in the car when it explodes after an accident, they think it's far safer to be thrown clear of the wreckage. In movies, when cars crash they explode. But that's just in the movies - it's a much better shot than the car just sitting there doing nothing.
