nah the headlights don't light up the road, to be honest, I'm not sure they should either, I don't remember seeing the headlights shining off the road when watching from onboard cameras in the rain, or the external cameras for that matter, the lights just reflected off the track. I think it's right, but many people don't.
one big complaint is the cockpits are too dark, which is true, but I just increased the brightness on my monitor and it looks fine
EDIT: I've didn't really check many servers online, I just went to one running a track I knew and went on it, gonna go for a quick blast now before i go out tonight though
