It would be great if one day we could have say a 2 hour race, with 24 hour time scaling. It should be enough time to see the transition go smoothly, and see how well it works.
The only problem I can see though is we'd need cars with headlights, so it'll have to be the default cars Maybe create a new profile, use the all cars/cash cheat and upgrade the car in every area so it's all equal? It's easily possible. Infact, you could probably get away with doing it at that oval with the infield section in the FormulaIS cars. If I remember correctly, most of the track is lit well. It's great when the lights turn on there. They flicker a good bit before they come on, and all at different times. Really looks stunning!
@marcl: I was skeptical about getting it after reading everyones comments, but I decided to go for it now, knowing I would eventually get it anyway for the mods. I think it's great! Havn't spent much time in anything else other that the F1-like car, and the F3 mod (which is great fun btw!). IMO, it fits nicely along side LFS as an alternative.
