Out of nowhere I could say, Lemax (I'm sure you know the name) hits us with a very well made piece of road based on a real location from Serbia. In his own words:
"Mišeluk is temporary street circuit near Novi Sad, Serbia. It is one of the most famous track in former Yugoslavia (now Serbia). Track is also very dangerous because of the big sidewalk curbs and steel light poles."
Track length 3.4km.
Thank you Lemax.
