'That's not enough for me' - Hamilton explains taking strategy into own hands

Lewis Hamilton has explained the reasons why he overrode Ferrari's call to pit in the Singapore Grand Prix, a mistake he says he "owned up to" and will work not to repeat - but which would not prevent him from continuing "challenging the norms".

Hamilton dropped out of the podium positions to sixth on worn tyres in the closing stages of the last race at Marina Bay after what proved the costly decision not to pit under the Virtual Safety Car, as the Ferrari pit wall had requested.
