Hi all friends. I have run my first race-weekend and I'm feeling like playing F1 2013 with other cars... The same graphics, the same interface, the same menus, the same celebrations after the race... But my question is... the red light behind the cars, means something or is only an ornament or decoration? It seems that the red light works in a random way... And the ERS when works? All the laps? Certain laps? For me every lap is similar, I don't notice any difference between them... Thanks in advance for your answers and help!!
