Japanese GP: Grosjean wants to move on from Webber shunt

Webber was livid after Grosjean sent him into a spin at the start of the race, an incident for which the Lotus driver was given a ten-second stop-and-go penalty.

Grosjean has been involved in several first lap accidents this year, and was given a one-race ban after he caused a spectacular first-corner shunt in Belgium.

The Lotus driver insisted he has been trying to be extra cautious since his return from the ban.

"Ever since I came back in Singapore my priority has been to be very cautious at the start, and I was watching Sergio [Perez] on my left to make sure there was no contact with him," said Grosjean.

"There was quite a big speed difference between me and Mark [Webber] as I came into the first corner which caught me by surprise and we collided. It was a stupid mistake.

"Mark came to see me after the race and was obviously not happy, but I apologised and we have to move on. We'll sit down and look at things again before the next race to see what we can do to improve these situations."

Grosjean finished the race in 15th position while Webber recovered to eighth.
