LOL, i was about to post in the trouble shooting threads about the blue guide lines disappearing on me when racing. No matter if it s spontaneous race or a in game race event there are times the line just up and disappears .For me it helps keep an eye on where and when turns are coming because after 600 hrs i still dont know every race inch for inch. So i think it should have a on / off switch as well. That way those who use it can keep it on and those who dont can turn it off. Right now it just randomly comes and goes when ever it wants. I just quite the race if i dont know the route by heart and the line vanishes.
