Massa missed out on a World Championship and he's taking action on it now.
"As reported by Motorsport.com, Massa is considering a legal challenge to overturn the result of the 2008 F1 World Championship. His concerns center around the 2008 Singapore Grand Prix. In an event widely known as "Crashgate," Nelson Piquet Jr. was instructed to crash to bring out a safety car to help Fernando Alonso's race. The incident ruined Massa's race, and he finished 13th, well outside the points."
