WHY SENNA IS CONSIDERATED THE MOST SUCCESFUL DRIVER EVER?

Maybe one of the reasons is because he is a triple world champion (1988,1990 and 1991) we sure that the most important thing is that he was so inteligent and also he had a diferent diriving style, more agresive than the other drivers.
He breaked later to take the curve faster, but this was a problem because the rear wheels will drift and maybe lose the control of the car, but he knew an amazing way to control the car, a great example is the qualifing of the Australian GP of 1985, he drove for Lotus. Take a look.
