We seem to be on the same idea at the moment, how do the files work together? I'm sure there is some kind of secret sauce in there somewhere, waiting for us to find it. Certain car and track combinations just seem to work really good while others are not so great. I'm still not able to point to what exactly it is that makes the difference.Greats informations, Peppelino. But the AI-Learning project is a plugin, something more elaborate and advanced, which requires more knowledge from those who know how to do it. The idea is great. It would be awesome to have this in SimBin games. For now, I'd rather know and "find out" more about how AI's behave, how the files involved with them (.HDR, .rcd, .plr, .tyr, .gdb, .AIW) work together , and share it with everyone. We can certainly improve and make AI's more "aware"...
