Classic San Francisco Street Racing Hot Rods Safety MovieThis 1950âs film chronicles how four high schools in the San Francisco Bay Area molded safe teen drivers by participating in the Mobil (now Exxonmobil) Economy Run, a race whose objective was to drive around the city within a designated period of time while avoiding penalties like speeding or violating traffic laws. The driver would be accompanied by a professional racecar driver, who would give the teens advice on how to drive safely and save gas. Scenes of the kids dancing in a malt shop and driving around San Francisco in vintage hot rods, street rods, and rat rods is included, but the real gem in this film is the great footage of San Francisco itself, including the Golden Gate Bridge. California teen drivers education sure was fun in the 1950s, and On the Run provides the experience of San Francisco history as well as drag strip racing history and old school hot rods.
