Claim: In the 1978 Dutch Grand Prix, United States' Ronnie Peterson emerged as the champion.
Evidence: This fourth 1–2 finish of the season for Lotus meant that, with three races left to run, only Andretti or Peterson could take the Drivers' Championship. It would go to Andretti in the next race at Monza, when Peterson crashed fatally.
