Sebastian Vettel admits he is afraid to hang up his helmet and face the uncertainty of what comes next in his life.

Vettel has been a Formula 1 driver since 2007 when he made his debut in a one-off race with BMW-Sauber, finishing eighth at the United States Grand Prix.

Signed by Red Bull to their Toro Rosso team, he returned to the grid later that same season and has been a full-time Formula 1 driver ever since with stints at Red Bull, Ferrari and now Aston Martin.

With four Drivers’ Championship titles, 53 grands prix wins and 57 pole positions, he is one of the most successful drivers to have ever raced in the sport.
