The issue is this is a problem that has been solved 2 ****ING DECADES ago!
Do you want to have a close 10 lap race without pitstops? Just give the car enough fuel and tires to go 10 laps. If someone wants to pit then let them pit, it's their loss. Gran Turismo ONE figured this out too. You could just make the pit-stop procedure streamlined with locked-in options or just disable fuel/tire wear for the longer races but instead, they just have to go for the nuclear option like a bunch of morons. I swear now, I got into project cars BECAUSE of the endurance racing. I loved the idea of jumping in an LMP2 car and getting the full single-player endurance experience of starting a race in the afternoon and finishing as the sky turns black. Instead, now we're just going to get the 24 minutes (or god forbid the 10 minutes) of Le Mans because any longer would possibly bore little Jimmy.
**** this. I live for endurance racing and I couldn't give two ***** about "QUICKLY OVERTAKE EVERYONE IN 3 LAPS OF BRAZILIAN STREETS" I want the racing that makes me exhausted and relieved like a 4-hour edging session.
