Cannon ball run definitly! those movies were awesome. I mean who else would have thought to put a 454 in an ambulence to evade the cops
But you missed something, there were three cannonball movies. The third was called Cannon Ball Run 3: Speed Zone. It was made in like the 80's and it's opening scene is a guy in a 25th aniversary countache running from the cops on some back country dirt roads then it cuts to a dad and his son at a lake and the dads trying to teach the kid to skip stones across the water and says it takes lots of practice. Then the countache comes screaming around a corner and out onto the dock of the lake and just starts skimming across the lake to the other side to escape the cops. Cheezy yes, but damn good
