Webber had his very own injury some time ago, when he broke some bones after mountain bike riding, but that's nothing compared to what happened to the Polish driver, he said.
"Compared to Robert, I had a scratched finger," the Australian driver said in an interview for Auto Motor und Sport according to the GMM F1 news agency.
But Kubica should be really patient when it comes to the recovery process for getting back into a Formula 1 car, Webber said, emphasizing that the Polish driver should consider himself lucky for surviving the accident.
"Our perception of risk is different to normal people," Webber said. "First of all, Robert should thank his lucky stars; to survive something like that is already a gift from god. From now it will be about the head. He is going to go through the ups and downs, because after three good days of training you have a bad one and you wonder if it's all going to pay off."
Kubica said in the first interview after his crash that he hopes to return to Formula 1 as soon as this year, emphasizing that his intentions are to compete in the current F1 season as soon as possible.
"He has to be patient, which for a racing driver is exactly the worst thing: we are hyperactive and he will want to see progress every day, as we do with our jobs. He just has to give it the time it needs," Webber concluded.
