Fernando Alonso has urged F1 to look into the possibility of introducing closed-cockpit cars in the wake of Jules Bianchi's accident during the Japanese Grand Prix.

The topic of closed-cockpit cars has gained momentum in the days following Bianchi's incident, the Frenchman suffering serious head injuries after colliding with a recovery vehicle during the Suzuka race.

Though the sport has shown a resistance to such a move in the past, Alonso says there is now scope and means to consider at least testing the possibility of closed-cockpit cars for the future.

"I agree to at least check and try and test the idea," he said. "We are in 2014, we have the technology, we have aeroplanes and samples that they use successfully, so why not think about it?"

Referring to his own accident at the start of the 2012 Belgian Grand Prix, when he came close to being struck by the wheel of Romain Grosjean's Lotus, Alonso insists the idea should not be excluded in the circumstances.

"The biggest accidents in motorsport in the last couple of years have been head injuries, so it is probably the part where we are not top of the safety. In my case in 2012, at the start, I probably could have died in corner one if it [wheel] had been 10cm closer to my head. If the technology is there and available, there is a possibility and we can't exclude it for sure."

It is a view that is shared by Alonso's former Ferrari team-mate Felipe Massa, who suffered a serious head injury during the 2009 Hungarian Grand Prix when he was struck by an errant spring from a car ahead.

"I totally agree with Fernando," he said. "I think it would be interesting to try. Definitely for my accident it would have been perfect, but for Jules I don't know. It could have been interesting for many different types of accident, but I totally agree with Fernando, I think it can be an option.

McLaren-Mercedes driver Jenson Button, however, is more hesitant, describing any move to a closed-cockpit design to be a 'very big change' for F1.

"It is a difficult one," he said. "There are positives in terms of a safety point of view, but this is F1 that has been open cockpit since the start of time, so it is a very big change for the sport to make. Safety is something that can always be improved upon so I am sure it will be looked at."
