Road America is a permanent road course. It is located midway between the cities of Milwaukee and Green Bay.
The track is situated on 640 acres (2.6 km2) in Wisconsin’s Kettle Moraine and it is located near the Kettle Moraine Scenic Drive. It has hosted races since September 1955 and currently hosts over 400 events a year. Of its annual events, 9 major weekends are open to the public which include 3 motorcycle events including the MotoAmerica (AMA FIM) series, 3 vintage car events, Sports Car Club of America (SCCA) events, the United Sports Car Racing Series, the Pirelli World Challenge, and the NASCAR XFINITY Series.
Road America is one of only a handful of road circuits in the world maintaining its original configuration being 4.048 miles (6.515 km) in length and 14 turns. The track features many elevation changes, along with a long front stretch where speeds approaching 200 mph (320 km/h) may be reached. One of the best known features of this course is a turn on the backside known as "the kink."
Road America's open seating allows spectators to venture throughout the grounds. Grandstands are available in several locations, as well as permanent hillside seating where crowds of more than 150,000 can be accommodated.
Real laps are still missing because I don't have infinite time to do everything. Tracks with little or no real laps have these estimated times added as placeholders. Few are simulations (which you describe as "gaming laps", perhaps incorrectly implying that they are non-representative), most are just calculations (including all estimates you see in this page).
