MONZA, Italy -- Formula One leader Lewis Hamilton is giving serious thought to the possibility of closed cockpits following the death of fellow British driver Justin Wilson in IndyCar.

Wilson died 10 days ago after being hit in the helmet by debris from another car. That came a month after F1 driver Jules Bianchi died following nine months in a coma after a massive head injury in a crash last October.

Speaking at the Italian Grand Prix, Hamilton says, "It's a difficult one. From one side I see closed cockpit as potentially the future. But growing up and watching the sport -- I grew up watching Ayrton's (Senna) generation of racing -- it's always been open cockpit. So it's difficult to change minds, but sometimes change is the way forward."
