I run a league with required pit stops in the races and I have seen lots of problems with pit stops and pit garages. Please include 30+ garage/pit spots in your tracks. That's all. rF2 is gaining a niche market for endurance racing, but too many tracks only support 12-20 garage/pit spots and that is a problem for larger fields. Thank you.
I can understand your request and it's basically easy task to do (0,5 - 1 hour AIW work and repacking), but... Many leagues already edit tracks for special sponsor billboards etc, repacks them and spread them out to members before event. Why not same time edit track's AIW file yourselfs for extra pitspots and garages for your needs before packing things up? It's not rocket science, really... Other point of view is realism. If track does not have those extra garages in real life, they are rarely modelled to track within original release just for large fields. If there are some extra object on track, it's 110% sure jeremiad starts immediately after release. Some of us are really tired to receive unnecessary criticism for some trivial detail (like missing bush, tent or some stain mark on asphalt etc.) after working on track project for six months and finally got it out for public...
