During the 1971 Cannonball Run, 2 strange things happened

and Arizona cop chased down Dan Gurney who was doing 140 in a Ferrari Daytona. He wrote Dan a speeding ticket. That is some serious determination... chasing down Gurney on a freeway.

the other thing was that a Chevy van was only 47 minutes slower across country than Yates and Gurney

the 72 cannonball was wan by a Cadillac over such powerful competition as a Cotton Owens prepped 340 Challenger
