Im testing with 95 f1 cars in your track and some cars stuck in the hairpin, and yes they back to the pit, then go again to the track, 1st test, i take this cars because is old conversion from rf, maybe other cars do better, and if i add different ballast and restrictor to f1 95 maybe pass well the hairpin in lap 1
to set a good race in monaco cars must have the minimal problems in lap 1
edit:
'91 cars can do all track 1st lap without any problem at 100% str 92% agr, so it's must depend on car mod, but modern F1 cars ai should make a better race here, because ai line its very good.
