The United States Grand Prix at COTA went green with Nico Rosberg leading Lewis Hamilton. Unfortunately, this already small field has been reduced to just 16 participants at the end of lap one.
Sergio Perez ran into Adrian Sutil, sending the Sauber into a spin and collecting Perez in the process. Both the Force India and Sauber were destroyed. The Safety Car was immediately deployed and the GP resumed on the fourth lap. When talking with reporters, Sutil blamed Perez for the accident.
