Video: News after the Japanese Grand Prix

Jenson Button was furious: Shortly after the start of the race, he asked for a penalty for Sebastian Vettel after the German driver had forced him onto the grass – "I had to pull back, otherwise there would have been an almighty crash." Vettel said he hadn't seen Button. What's your take on the incident?

More trouble for Lewis Hamilton: Felipe Massa demands another penalty for the McLaren driver after the Japanese GP. The two drivers made contact once again at Suzuka, damaging the Ferrari slightly in the process. Is Hamilton too hard or Massa too soft?
