The reigning MotoGP world champion's title defence was dealt a major blow when a violent accident in a very wet second practice for the Dutch Grand Prix left him with injuries that will rule him out of at least this weekend's race.
Lorenzo said he only had himself to blame for the incident.
"I think I was too confident, at the moment of the crash I was very fast and felt very strong, but maybe the conditions weren't the perfect ones to have this high confidence," he admitted.

"I entered the corner faster than the previous lap and I think I touched a patch of water, or maybe aquaplaned which made the rear wheel light and touch onto the white line, making it a lot worse - which is why I crashed."
He dismissed any thoughts of an 'Assen jinx', having been taken out on lap one of the Dutch race for the past two years.
"I don't have anything negative with this circuit, just bad luck or in this case, too much confidence," Lorenzo said.
"You must always be optimistic, things could be worse and I will try to recover as soon as possible."
Lorenzo has now flown to Barcelona for surgery to be carried out.
He is currently seven points behind championship leader Dani Pedrosa.
