On the full alt. circuit, there is a white line that crosses the track, a timing line. It causes the lap to foul. How annoying! Here’s a link to a vid:
It dirties your lap for drafting? That’s a farce if it does. I am not sure I was though, I was the same distance behind the whole lap and his was dirtied in the same place, I think. All I heard on the mic was a howl of frustration from him in the same spot.
We’re having fun, just spending laps out maneuvering each other but making clean laps with the odd reasonable time. I like making clean laps, even when I’m racing someone.
