In that driving show on speed with Tommy Kendall, they had 3 pro racing car drivers take the m3 through the tests they put you through in m school. In the Slalom test, one of the drivers remarked that they had the fastest time with traction control on.
Traction control was banned in F1 in 2008. I doubt it was because traction control was making drivers too slow.
