Once watch some "famous" ex-racing driver testing the CLS55 in the US against Mika Hakkanen. Gave the big "I like to turn the traction control off - or as I call it the fun police" - then Mika said something like "but the car is a better driver than you will ever be" and demonstrated it by blowing him of the track while he (Mika) still had the traction control on!
Even worse than "one time" (no-time) ex-F1 driver Tiff Needell.
