I could see that happening, Perez has had a few early brakes, Massa was just unlucky to be there. Perez should probably have stayed on the right hand side though.
Goodness, what a crash. Good to see they're both okay.
Is there any doubt now that Ricciardo is the better driver right now? More intelligent, more comfortable in the car, better on the tyres, and still seemingly better at extracting the best from the car over a single lap. Poor Vettel.
