Having watched quiet a bit from the replay of the previous race made me think that we need few things in the rules.
Some of these have already been mentioned, but I'm not sure in what degree or how much of these - I've spend loads of time going through the replay and writing (and reading) the report, so please excuse me for not being in the mood for doing some more reading.
- The car(s) involved in an incident, or in any other way causing the safety car to deploy should not take part in the formation. In this case a driver had a puncture and was driving slower, meaning he was holding back other drivers, including Dynamic Racing who were on 2nd at that time.
This rule should however only apply to those who can't drive safely due to damage, but especially if the driver will be entering the pits because of the incident.
- when a car limps back the pits, this driver should be required to do everything in his power to avoid slowing others down, while of cause being on the track. The driver should also be required to drive off the racing line, except during turns where crossing the line is necessary.
- a driver causing, or getting too close to cause an incident while the safety car is out should receive a severe penalty. Since multiple cars are allowed in IGTC, exploiting this to for instance take out the opponent is a possibility. I recommend something like a 1 lap penalty and a warning. After 2 or maybe 3 warnings, that car should be banned for the rest of the season, and the team should not be allowed to enter with another car and a new set of drivers.
Even a slight touch should technically speaking be enough to hand out penalties and warnings.
- if a incident similar to the one on Westhill during a SC lap occur, marshals should either pay close attention to the queue order, so the places can be resumed correctly - or ignored them completely and let the cars resume naturally, but without disengaging the limiter.
In the previous race the leader was allowed to resume his place, however some (didn't look) may have gotten mixed around - this approach isn't completely fair.
- chatting isn't allowed, and especially the marshals should remember that the race isn't over till the very last driver crosses the finish line, before congratulating etc. It's disrespectful and distracting for those who are still racing.
