Mercedes not aiming to put an end to family feud: Wolff

Mercedes will not try to halt the fierce rivalry between Formula One world champion Lewis Hamilton and Nico Rosberg, team boss Toto Wolff said.

The feud that came to a head when Rosberg drove into Hamilton on the second lap of the Belgian Grand Prix at Spa-Francorchamps last August was good for Formula One, Wolff said.

But the British and German rivals must not cross the line of what is acceptable again.
