Nelson Piquet Jr did about a season and a half in F1, being replaced midway through 2009. After he left, there were allegations that he'd deliberately crashed his car during a race in the previous year so that his team mate, Fernando Alonso, could win. At the following trial the FIA (F1's governing body) gave him immunity in return for his evidence. He claimed that his team boss and the team's chief engineer had come up with the plan and that he'd been pressured into it. The team boss and the engineer were both suspended from the sport, although the bans were subsequently overturned on appeal. Piquet Jr had talks with a couple of other F1 teams, but decided to move to NASCAR when he failed to get a drive. His father, Nelson Piquet, won the F1 World Championship three times in the '80s and entered two Indy 500s after he retired from F1.
