Coulthard backs women F1 drivers

Red Bull's David Coulthard believes there is no reason why women drivers cannot be Formula One drivers.

"I'm a great believer that ladies have an equal opportunity to race as men," Coulthard said.

"There's no reason at all why they shouldn't race with men. There's no physical or reaction reason."

"More men get into it, because more boys get into it," said Coulthard.

"My sister was naturally a better driver than I was."
