Massa and Sato clash in dramatic practice round

Felipe Massa has branded Takuma Sato “completely mad” after the duo were involved in a practice dust-up ahead of this weekend’s United States Grand Prix.

Sauber driver Massa and BAR star Sato collided at the first corner of the Indianapolis Motor Speedway, and both blamed each other for what was an unnecessary incident during the afternoon practice session.

Both drivers were doing 200mph down the long pit straight when Sato chose to pass Massa on the inside as they approached turn one.
