The most common mistakes made by drivers, for which they may be penalised by the stewards:
Failure to record or stream their on-board camera (POV) footage
Qualifying,
If you are not on a fast lap, you must let drivers behind you pass.
Race. Blue flag,
We do not have ghosts. As in real: if a driver is planning to overtake you on a lap, the game will show you a blue flag. You must carefully leave the racing line without sudden braking and let the driver pass - example.
Leaving space for another driver,
We always leave space in a battle if there is another car nearby (red arrows). You need to leave enough space for your opponent's car to fit.
Reset to track - prohibited,
Retire from session,
Only allowed in pits.
