'Lucky' Kubica hopes to race at Indy

"As you see I'm quite in good shape and I'm hoping (to be) going to Indianapolis if the doctors will say OK for my driving," Kubica told reporters outside Montreal's Sacre-Coeur Hospital.

"I feel very good. I was very lucky - big accident, but fortunately nothing hurt," he added after walking gingerly down the steps of the hospital.

Kubica said he remembered "nearly everything" about the crash.

The accident occurred when the 22-year-old BMW Sauber driver's car made contact with the rear wheels of Jarno Trulli's Toyota on the approach to the hairpin on lap 27 on the Gilles Villeneuve circuit.

His car took off, flying through the air and slamming into a concrete wall before barrel-rolling across the track.

The crash shattered Kubica's car to the extent that his feet could be seen through the sheared off front end of the vehicle.

A BMW spokeswoman said Kubica, who suffered only a sprained right ankle and light concussion, had driven himself away from the hospital.

The Pole will have a mandatory fitness test at Indianapolis on Thursday before being allowed to compete in the US Grand Prix, but the team were confident he would be racing.
