I can't proove this but I'm sure the start lights on multiplayer races aren't syncrhonised. Did a race around Watkins Glenn in the GT3's with a friend. He left the start line about half a second before me. I told him "surely you have a penalty for that". He said his light was green. Anyone else noticing this??
Desyncs can unfortunately happen from time to time. Something to look at down the line for MP improvements.
Happened for me too - at both examples, others started around one sec earlier than me, while I still had red light.. But hope MP will get better on v1.5
