I've added the ability to race against the AI, but I think the racing lines and corners could be improved greatly. I've also added grip. I've been using GT3s for racing.
I know the track is not perfect, but it's still enjoyable with its elevation, turns, and bumps, which add character to the track. Once you learn how to use everything to your advantage, it becomes a really fun experience.
I would really appreciate any helpful feedback.
