I've only just heard of this event this morning, and I am fascinated. They close a section of highway and race up and down a section of straights with chicanes, a 180, and use the on/off ramps on the other end. Surely someone should mod this into a sim?!

Onboard laps I found on YouTube from last year's event:
In this video you see where they refuel the cars about 5:00 minutes in. Its literally a gas station across the street from pit lane. Also, this driver's lack of heel/toe is driving me crazy.
