Michael Schumacher drove the #32 car in his first ever Formula 1 race on August 25, 1991. He competed in five more races that season, driving the #19 car.
Ralf Schumacher made his formula one debut in the 1997 season for the Jordan F1 Team. He drove car no. 11 in his first season. He finished his debut season in 11th place overall with 13 championship points. His best finish was the 3rd place he achieved in the Argentine GP.
Michael Schumacher actually won the Formula 1 World Driver's Championship 7 times; 1994, 1995, 2000, 2001, 2002, 2003 & 2004. He won 91 races and had a total of 1,369 points before retiring at the end of the 2006 season!
In my opinion Yes. He has won the most number of races (71) for any driver and also holds the record for most number of driver's championships (7) which statistically makes him the best formula one driver till date.
he knows that this number where all his basketball career begins..
As far as his NBA career is concerned, he never wore jersey number 9.
