Grosjean: Errors helped me improve

Romain Grosjean believes the on-track troubles that marred his first full season in Formula 1 have helped him realise how much he still has to improve for next year. The Frenchman, who is set to remain at Lotus even though his new deal has not yet been confirmed, got involved in a spate of first lap incidents in 2012 - and was handed a one-race ban after the Belgian Grand Prix for causing a crash. Although he avoided further trouble on his return, Grosjean says that the post-season period has delivered him proper time to reflect on the areas where he must do better in 2013.
