This track is very nice so far. The AI is leavig the track at some places and not taking advantage of the full track width on others. So I guess you need to add some sidelines. There are trackside objects missing (see here http://www.speedwayandroadracehistory.com/augusta-international-speedway.html). And please make the lake look nicer. I hope you will continue this project (and then fill in all info in the ui_track.json so we can keep track of the updates).
