Yup.   This is a real racetrack in Italy.   The famous Autodromo Nazionale Monza.   Right here in Flight Simulator.   The shape of the track is very accurate, as it's drawn right over the arial photography.   The elevation, however, could by off by as much as Asobo's elevation data is off.   YMMV. 

I've included both the main track and the oval, but only the main track is timed with Race Tracker.   The oval is included just for grins, as it does not have the banked corners as the real track does.    Also missing is the bridge where the oval crosses over the main track, as the SDK does not yet allow me to put in a working bridge.    So while some limitations apply, this is still fun to race on.   I added an airport runway in the infield so you can spawn here, fly here, whatever scenario you'd like to play.   Like the other real-life tracks I built, this can be run with a variety of land-based vehicles.  Slower ones result in much closer racing.  

That's all I've tested it with.   Hopefully more options will be released....
