Budapest: Jenson Button made clear on Sunday that hot-headed Frenchman Romain Grosjean was entirely to blame for their collision during the Hungarian Grand Prix. (Read race report)
Grosjean, of Lotus, collided with Button's McLaren during a badly-judged bid to pass him on the 24th lap of Sunday's race in which he was penalized for another incident and ended up finishing sixth. Button was seventh.
In their collision, it appeared that Grosjean tried to follow Sebastian Vettel in overtaking the McLaren, but misjudged the space available and required.
