The Interlago circuit was a safety threat to the 1979 Brazilian Grand Prix drivers .
But in 1980 , the neighborhood of Interlagos was becoming increasingly run-down and the growing slums surrounding the circuit did not look good for the glamorous image of Formula One ; and the drivers were dissatisfied with the safety conditions of the very bumpy 5-mile Interlagos circuit , and Jody Scheckter attempted to stop the race from going ahead ; but this did not work and the race ended up being won by Frenchman Rene Arnoux.====Jacarepaguï¿½ , Rio de Janeiro ( 1978 , 1981-1989 ) ====
