you don't have to participate in races that take longer than you're ok with . I too prefer the endurance races that are less than 12 hours, but I still play the 24h ones just because it feels good when you're done. I think we should have a 24h race for spa, nurburg and la sarthe, and also dozens of shorter ones. When the endurance is just 2-5 hours, it's not really a drag to have a lot of events with different rules and limitations. 4 hours of rwd on wet tracks, 4 hours of MR cars at night, 3 hours in a pre-1970s car (no 2j!), 400, 500, 600 PP limit endurances, anything, really. Designing these races isn't a lot of work. You've already made the stuff that takes a lot of effort to make, this is just mixing and matching what's already in the game. Accelerated time is a decent idea, but when a whole day is compressed to 24 minutes, that's too extreme. On Nurburgring, you don't even get a single lap in the same kind of lighting. You start in the morning and after a single lap it's already nearing twilight, what's up with that? 24 hours compressed to 4, 6 or 8 hours would have felt much more "real".
