I was always amazed as a kid that the traffic lights knew when to change. I imagined that there were little tiny people inside (I saw them with little elf-type hats and shoes) who sat there looking out over the road. When they saw cars coming, they'd hit this big button that would change the colors of the lights. I believed this until I learned about the sensors in the road at about age 12.
