I can't see any cars (not even my own) on the HUD line (press 4). This happens with all the mods and cars. It's just empty line, no matter what session, and if I'm alone on the track or not.
Have you install all your GPU drivers? Have you a modded version of rF2 (HUD mod's ect.)? I had this problem to, but in a another game ! I install all gpu components and my problem was solved.
player.PLR [ Graphic Options ] Automap="3" // 0=off 1=race-only 2=non-race-only 3=all sessions making value "0" will remove the cars icons.
Ah, thanks. I accidentally turned if off thinking it was, well, a map of the track or something other arcade style thingy...
