8. Michael Schumacher
When the most successful Formula One driver of all times retired in 2006, many wondered what would he do in his spare time. Unsurprisingly, he decided to stay on the track, but instead of Ferrari, he would race a Honda Fireblade, as well as a Ducati. He even had some success in several exhibition races. Hopefully, he will recover from his skiing injury and we will see Schumi at the track again.
