Michael Schumacher vies with Tiger Woods as the world's best-paid athlete--last year they earned $75 million and $78 million, respectively. But while Woods' performance has been wobbly in the past two years, the German Formula 1 race driver has the opposite problem: he can't stop winning. Schumacher, 35, has been world champion six times, more than any other driver, and is on his way to his seventh title. In his 10-cylinder, 2,997-cc, 853-horsepower, carbon-fiber red Ferrari, Schumacher gets as close to perfection as is humanly possible at 220 m.p.h. The sport's organizers want to slow him down.
