What is Michael Schumacher's driving style?
It is an Aggressive Oversteer driving style. This is why.
Michael Schumacher is known for being aggressive on the steering and for preferring an oversteery car setup. He has lots of experience driving in the F1 eras where you almost always had to be aggressive to be fast. This shaped his driving style to the way it is.
In the 1990s, the cars required the driver to be slightly aggressive to stay on the limit of grip. Schumacher had the innate ability to adapt to this and drive on the limit. He adapted to a smoother style around the 2000s F1 era as the cars didn’t like aggression.
