Never heard such drivel. You cant compare drivers from different eras. different cars. Different styles. So therefor your own arguement says that the ONLY way you can tell who is the best driver is by comparing him to others in the same kinds of cars at the same time. That means that the final determining factor is how many wins or losses you have. This automatically makes Schumacher the best as he beat people driving similar cars in the same era. Geez learn basic logic.
