Bottas questions radio rule changes

Williams driver Valtteri Bottas has questioned whether the changes to Formula One's radio rules are enough.

Although he has been unaffected by the new rules, he said that the punishments handed to those who brake the rules aren't enough to put people off doing it.

"For us the rule has been no problem as we haven't had those kinds of issues in the races, so as long as we don't have any kind of those problems then it's fine," he said.

"But once you hit the problems, I think Nico [Rosberg] got only a 10 second penalty with multiple advices, so I would guess staying on track and taking a penalty would be less of a penalty than coming into the pit lane for advice."

"So unless they are going to change the rule on how big penalties they are going to give you for staying on track, I don't see a point in coming into the pits."
