Very safe. After an accident of such a magnitude, Kubica has recovered. And, he wants to compete in Indianapolis :)

I was really impressed with the Medical crew. They were extremely fast, and were there in the scene of accident within seconds. Its interesting to read what the doctor says

Dr. Ronald Denis, the head of the trauma unit at the hospital, said he was amazed the young driver survived.

“I was at the [racetrack] tower, and to be honest with you, when I saw the accident I thought we were going to arrive there and he would be dead,” Denis said. “But when we arrived there, he was talking to us, complaining of some pain in his right ankle. He was breathing, talking.”

I like these rookies. Kubica, Kovalan*.* and Lewis, of course! They make the races very interesting and entertaining. It would be better if the boring overhyped guys like Button are kicked out of F1.
