2012 saw Grosjean have several crashes but he and others state that there has been a vast improvement this season.
Aug.23 (GMM) One year ago, Romain Grosjean was F1's 'first lap nutcase', and soon to serve a rare race ban after his latest crash at Spa-Francorchamps.
"Yes," the Australian is quoted by the Russian website f1news.ru.
"But he had no other choice. This year he is coping with the problems better, but let's face it -- after last season, it (improving) wasn't too difficult.
"In Budapest he made a mistake in the situation with Jenson Button, but his overtaking of Felipe Massa was really good," added Webber.
So, with his Lotus teammate Kimi Raikkonen strongly linked with a move elsewhere, Grosjean is expected to stay at the team in 2014 -- perhaps as the new lead driver.
He agrees with Webber that he has been much improved this year.
"Well, a different state of mind, I think I've progressed a lot and worked on that and I think the 2013 starts prove that I did my duties," new father Grosjean said on Thursday.
