"Most of our traffic and motor safety problems are created by a few childishly inconsiderate drivers"
In 1954 Garfield Elementary (Arizona) offered drivers education to kindergartners.
The whole thing kicks off with a police officer performing a magic show to present the basics of driver safety like explosions and fire all in an attempt to show kids "the man in the blue uniform is your friend" (when he isn't scanning your license plates).
Do yourself a favor and watch the entire video. It's amazing and shocking to know that in America we once taught people how to drive before we taught them the alphabet.
