I just learned that Burt and friends were 5 years late to making a movie about a Cannonball Run, in 1976 David Carradine made one

                              1976                                                             1981

David Carradine played Coy ‘Cannonball’ Buckman, a professional racing car driver looking to get back on the circuit after a heavy fall from grace. He is not long out of prison and itching to claim the $100K kitty on offer for the winner of the Trans-America Grand Prix, an illegal road race from Los Angeles to New York. He uses a 1970 Trans Am

Which reminds me I posted images in 2015 from the wheel changing scene where he uses a guard rail to get the car off the ground because he either doesn't have a jack, or he doesn't have time to jack it up
