Some F1 teams work to manipulate the performance of their two drivers, according to Fritz d'Orey.
Now 73, Brazilian d'Orey contested Grands Prix at the end of the 50s and remains an eager spectator.
He said on the SporTV programme 'Linha de Chegada' this week that Ferrari manipulated the situation some years ago to ensure Rubens Barrichello was not as fast as his number 1 teammate Michael Schumacher.
"Alain Prost told me at a dinner in Paris that they did it to Barrichello when he was going too strongly in relation to Schumacher," he said.
Another legendary Brazilian driver, 73-year-old Bird Clemente, agrees: "That's right. I'm sure it still exists.
"The team as well as the sponsors are making a big investment. To some extent, it is theatre."
