Nico Rosberg says the intensity of his competition with Mercedes teammate Lewis Hamilton makes it difficult for them to be friends.Following collisions at the Spanish and Austrian Grands Prix this season, the relationship between Rosberg and Hamilton has come under intense scrutiny. The pair have known each other since they raced go-karts together in their teens, but Rosberg says their relationship has become increasingly intense since they started going head-to-head for the world championship.I have huge respect for him but, well, were not best friends at the moment, Rosberg told the Guardian.Were just both so competitive and that makes it difficult to be friends because the competition is so extreme.It was the same back then [when we were karting]. How many pizzas could we eat? Who could run fastest from the lift to the hotel room? It would be competition all the way but there was not the surrounding influence with a team, the media and money. That makes it difficult now.Rosberg currently leads the championship by one point after seeing a 43-point lead eroded over the last five races. But Rosberg does not believe 2016 will be the last big chance in his career to win the title.I dont think of it that way. Its just a great opportunity, he said. Of course it helps for motivation when youre fighting for wins. If we were 12th and 13th its not the same. Fighting for the title is incredibly intensive. The learning curve is steep initially.Ive learned a lot and made massive progress. The actual driving doesnt change much but its such a difficult situation because youre racing together and, at the same time, against each other. Thats a unique challenge.
