Take it easy. 9 wins in a row in motor-racing history are more likely made by super power of a car&team. Not by any driver.
In this topic AA was just so lucky to have such dominant car&team. Just like Fangio had in other seasons, or like MS in 2002, 2004.
Quick fact: same driver, MS, but without dominant car, just loose to his team-mate 3 seasons in a row: 2010-2011-2012. Really?
