The Gumball Rally
trailer: https://www.youtube.com/watch?v=tKF390MNM7k
This 1976
movie is about an illegal coast-to-coast road race based on the real-life Cannonball Run. Starring Michael Sarrazin, Norman Burton, Gary Busey, John Durren, and Susan Flannery among others, this flick actually predates the Burt Reynolds
Cannonball movies by several years. If you’re in the mood for a
fun car-focused action-comedy, sit back and enjoy this classic.
From the era of US national speed limit of 55MPH....if you can believe they did that BS.
So instead of speeding at 90 MPH like today, people did 7omph.
