In another sim I've used recently, there are a couple of long road tracks. I've enjoyed driving them, but I do prefer circuits and I was wondering if such tracks could simply have their end 'stitched' to their beginning. Even hill climbs could be infinitely long that way.
Times would then have the advantage of a flying start on laps >1, of course.
Or does a 'simulator' have to be confined to real life possibilities?
