Magic Highway U.S.A.

Overview

The theme of this is the significance of the American highway, featuring the history of motoring, which explains that to drive the first cars was quite an adventure in itself, due to awful roads (which back then were not much more than rutted wagon paths) and the scarcity of fuel supplies and spare parts, not to mention the lack of useful maps and signposts, resulting in short drives turning into day-long affairs.
