At Silverstone the drs zones 2 work in Practise and Qualif but not in race
I just tested it. DRS zone 2 works, but I made a mistake. You have to be much closer to the car in front (approx. within 0.5sec) at the detection point for you to get DRS.
I need to make further adjustments. I will upload an update for Silverstone and Sepang tomorrow. I'm still learning as I go.
