That cracks me up the most, people that think it's a weight issue and there is some sort of scale in the pavement. It's actually coiled wire forming an electromagnet sort of circuit to detect metal.
I thought that for years...  In my defense, I thought this because that is what my Dad (who ironically taught electronics for a living) told me a long time ago. It was not until 4 or 5 years ago that someone set me straight.
