[Jaroslav Černý]

AC penalties are nonsensical and unrealistic. The slowdowns for cutting are an abomination. It's probably better to disable them altogether and use a server app to issue penalties in a custom more controllable way with drive through, stop and go, etc. KMR also has similar features where you're allowed a certain amount of going off track even a little when AC's useless detection doesn't register it yet and you collect cut poins, do this too much and you get kicked I think but it could just give you a DT or SG instead.

The severity of penalty usually goes like this:

drive through
stop and go
stop and go with varying wait time
disqualification - black flag (aka drive to pits and stop, game over for you, disconnect)

It can be fixed but since there are no major leagues in AC due to lack of driver swapping that killed league racing for AC the apps and servers are not commonly setup to remove stock AC penalties and improve them with custom more realistic and safer ones.
