Lewis Hamilton unsure who was at fault in Brazilian GP crash with Valterri Bottas

Lewis Hamilton is adamant that the collision with Valtteri Bottas that earned him a costly drive-through penalty in the Brazilian GP was a "racing incident".

While Bottas was not heading for a points finish at the time, Hamilton's penalty and eventual ninth-place finish, combined with Webber's runner-up position, meant the Mercedes man lost out on a first top-three championship position since 2008. Hamilton, however, reiterated that helping Mercedes to second place in the constructors' had been his only focus at Interlagos and, in something of a back-handed compliment, suggested the Red Bull driver's clear car advantage meant he should have finished ahead of him anyway. "I don't care! It doesn't really matter," Hamilton insisted when quizzed about third place. "At the end of the day he [Webber] should be there because his car was so much faster all year. In my position where I was I would have stayed ahead. We would have been equal [on points] actually but I would have been ahead because I had a win. But it's not a big deal; you don't get a bonus for it and winning is the only one that counts. "Second place in the Constructors' was the most important because that was what the team deserved and I really wanted to contribute to that. So I'm glad I at least got two points today." After his first 12 months away from his long-time McLaren home acclimating to his new surroundings at Brackley, Hamilton now heads into the winter hoping for a much improved campaign in 2014 when Mercedes are predicted to prosper from a dramatic change in the regulations. "It hasn't been a spectacular year in terms of my performances but hopefully there is more to come in the future," Hamilton told Sky F1.
