The guy in the video, who now works for TopGear (his name is Tiff Needell) was a LeMans 24hrs Race winner...So seeing him powerslide a car at a 100mph and talking at the same so nonchalentely is understandable. He has also testdriven the Ferrari Enzo and during the 5mins time he was allocated as were all the other international drivers for other magazine, he made the best lap time of all also while talking on camera. Very impressive!!
To my knowledge, Top Gear makes the best tv program about cars I have ever seen.
The drivers are very very good and all experienced race car drivers...Another one is Jason Plato who is a well known race car driver in GB.
