I used to think cars drove themselves and automatically knew when to stop at stop signs, which way to go, etc. (this was long before Knight Rider)
A childhood belief about cars

others believed things like this
- I used to believe, driving in front of all the other cars on the highway, Knight Rider was leading the pack.— Michael Kolassa
- My little sister's imaginary friend was Kit the talking car from that show Knight Rider.Anon
- Having seen enough red octagonal STOP signs in my time, I used to look out for green circular GO signs.— Gary
- I used to believe that the sky had stop lights and road signs floating about for the airplanes.
— LoonaSM's - I used to think that Mice controlled the Stop lights and crosswalk signs.Anon
- I thought if 3 cards stopped at a 3-way stop sign then they had to stop forever until Christmas.Anon
