September of 1971 NASCAR Driver Bobby Isaac made history setting several speed records at the famed Bonneville Salt Flats. In the iconic 1969 Dodge Charger Daytona after the car was banned from NASCAR in 1971, Isaac's car owner Nord Krauskopf with help of USAC decided to give the car a fitting send off. Bobby Isaac and his pit crew led by legendry Crew Chief Harry Hyde set 28 speed records several of which still stand today.

Or the time that he “gracefully” retired from the lead with an oil leak at Trenton because Parnelli Jones had been allowed to beat him at the Indy 500 with one but he needed to show that he was a good boy that would follow the rules even though he hadn’t been black flagged.
