I just discovered this late-1970's "gem" of an educational film about street safety for kids called "Ricky Raccoon Shows The Way." I saw it at Rifftrax Summer Shorts Beach Party last night.

Lots of 1960's and '70's cars and trucks, and a Southern Railway diesel locomotive.

There are other shorts from this collection that have vehicles that could be added.
