I don't think the number of cars is the big issue.
-The twin SC feature just doesn't work, it has artificially split competing packs.
-The waiting for the next train after a pit stop is a joke, the cars already have to drive to a delta under yellows so why force another 2 minute loss?
-As always and just like lemans track repair takes too long.
-Tarmacking run-offs is all well and good but without drainage the areas turn into lakes and hydroplane cars into the barriers.
-You have the virtual safety car system, USE IT!!!
