Trulli shocked by Kubica's crash

BMW Sauber driver Kubica made contact with the rear of Trulli's Toyota on the approach to the hairpin on lap 27, his car going off the track and slamming into a concrete wall at high speed before going into a series of rolls.

Trulli said he had done nothing wrong, but admitted he was very worried about the Pole driver.

"I hadn't seen him. The last time I saw him, he was on my left hand side on the other part of the circuit, then he must have hit me on the other side because I had a cut on my right rear tyre," Trulli told reporters after the race.

"So I think he must have moved or he had a failure - I have no idea honestly.

"Honestly, I didn't move - I kept on my line and didn't even move," he added. "The last time I saw Robert he was on my left hand side and apparently he turned right and I had no idea what he was doing. I just kept my line.

"I saw Robert's manager and he was the first person I saw afterwards. I know I am a driver but I am also a human being and I am very shocked.

"I kept my line and I was hit up the  back. I was pretty shocked for one stage because we had safety car and medical car and I didn't have much information and I had a flat tyre. So many things that I couldn't get a grip on."

Kubica was flown by helicopter to a hospital in Montreal after he was extracted from his wrecked car.

Although further checks revealed the Pole had escaped serious injury, Trulli said there were lessons to be learned about track safety.

"Until the accident doesn't happen, everything is fine and we can calculate everything but I've seen the accident today and it was massive and there was something pretty wrong  there with the angle of the barrier," Trulli added.

"Obviously, we try to do our best as drivers but it was a missing element that none of us expected to see - unfortunately it happened and the circumstances can be quite bad.

"This must be an experience for future races on this track and also street circuits where it also raises a problem. They are always safe  as long as there are no accidents or special incidents - like Robert's - what happened in the race I don't really care anymore because honestly I'm shocked by what I saw what happened to Robert.

"I don't care about how the race went; I don't care about the safety cars; I don't care about anything."
