I was just at Laguna Seca this last weekend, and they always run the Star Mazda series before the big ALMS race there. Star Mazda are small open wheelers bit a decent amount of power and speed.... always fun to watch.
At the end of the race, several top finishers just had a little fun at Turn 2 (the hairpin) and were actually drifting or 'power-sliding' through the hairpin. Was pretty cool, because they could hold it fairly well.... but it ends quickly because the car either regains traction quickly, or they need to stop because it will slide sideways like Montoya.
It's very possible to power-slide, no doubt, but probably impossible to just do proper drifts by throwing the car around and causing the slide.
