Since it was brought up in the Singapore thread....
...I would be up for a Thailand night race if it was designed to be a challenging race track, not a glamour shot where it's more albert park or montreal than Monaco or Valencia (as astracrazy put it), with half to 1/4 the wattage of Singapore.
Have a pseudo-dark race where each team is subsidized by the FOM or whoever to create special front/rear packages that have lights in them, so that they're an godly mix between F1 and LMP.
F1 cars, racing through the night on barely lit high-speed circuits peering through the dark on flat beams of white LED light, avoiding the thin, red lines out the rear of other cars, and the grandstands being outlined by rows of LEDs marking the edges and exit paths.
Imagine an entire field of F1 cars laying down beams of light like Tron. Something like in Cars 2
THAT would be the highlight of my season.
