I saw this in the rFactor 2 description: Dynamically laid rubber increases grip throughout racing session(s) Rubber chunks (“marbles”) roll off tyres and can affect grip 1. Does the marbled line end up where most people drive (calculated median where marbled line end up) or will it always be the best line that emerge? 2. About the "rubber chunks", is that just physics side or is it visible to the eye? I never seen rubber bits in corners after many laps so im just curious how this works. Maybe that there is even less grip outside the marbled line on the side where cars put their weight on?
