This picture, trackmodders is a very good sample on how to mark the change of direction on a race track. Longfort'67, Las Vegas and lots of other tracks do suffer from this, "direction problem" when using VR. While here you see brake marks, direction sign boards and a different tarmac colour. Maybe not in monitor mode, but in VR it's very difficult to determine this kind of sharp bent in a split second at full speed and every marking is helpfully to avoid driving in a straight line to the wrong section. So track modders, I know most do not have VR, please introduce the markings for VR users, very helpfully for VR enjoyment.
Thanks
