Parnelli Jones won the Indianapolis 500 despite his car (nicknamed “Calhoun”) spewing oil from a broken tank for many laps. Officials put off black flagging him until the oil level dropped and the trail stopped. Colin Chapman, whose English built, rear-engined Lotus Ford finished second in the hands of Scotsman Jim Clark, accused the officials of being biased towards the American driver and car. Additionally, driver Eddie Sachs was punched by Jones at a victory dinner after Sachs told Jones that his win was tainted.
