How do you tell how much kers you got and if you can use drs in cockpit cam?
When you hold down the Kers button in cockpit view you will see the LCD on the wheel count down from 400 as you use it up.
You can tell When you can use DRS by the little green light on the wheel being on, when you activate DRS it flashes, when you next brake DRS automatically deactivates itself and the light goes back to being permanently lit or turned off if you are outside the DRS zone/further than one second behind car infront
