So I had an idea for a GTA V race route https://www.youtube.com/watch?v=YzDdl-v36OA Essentially it just follows the Chiliad train track all the way back to that one station. Theres some randomness because theres street crossings and choke points as well as the impending threat of a train fucking you up. I think we may reverse the route because it seems the train goes in the same direction as I did in the video.
