|Model Car 9 (1939)|
From the film's narration:
And now we see an enlarged section of 1960's express motorway. Along the ledge of this beautiful precipice, traffic moves at unreduced rates of speed. Safe distance between cars is maintained by automatic radio control. Curved sides assist the driver in keeping his car in the proper lane under all circumstances. The keynote of this motorway: safety. Safety with increased speed.
Each NBG sub-shaped car or bus barrels along it its own curved track, like a ball in roulette wheel or a luge. There doesn't appear to be any provision for exits or on-ramps. Who needs 'em? (It would certainly solve the driving while texting problem.)
