Lapping is what I have become very much used to by now and it is very rare that the situation is problematic. Especially if it is in a situation where you have enough of a lead on the driver behind you there is time to select where to pass and how to pass. If possible I also sometimes do not lap people as soon as I can if the guys are having a battle and I have enough of a lead.
The tricky bit is when there is a car right behind you and you are in a battle for position. Than you need to get past the cars that are being lapped as quickly as possible and it is sometimes very tight or you HAVE to go for a move that is riskyer than you would want it to be.
That is why I alway flash my lights allready from a bit of a distance and than again closer up if I see that the driver has not seen me (usually you can see that when getting closer). Most of the cases work, rarely the lapped guy mistakes me for a car that is batteling him for position but usually than everything works out. Imola and the GT40 was more of a strange case - from my point of view it seemed that the lapping wasnt recognised as there was much line changing going on ->even more so than sometimes when there really is a fight for position. However I was able to get past without big problems as my car was up to the task. If I would have been in an Escort however I wouldnt be able to pass due to the fact that I would be loosing too much ground on the straights and would than be held up in the corners - so couldnt get a run again on the next straight.
We have disscused this subject many times before and that is also why there was a rule adjustement.
I am not a fan of the rolling start - I was against it, but I have to say that when we get it right it does work very well against the T1 pileups. The problem I see really is that the people dont keep together enough on the out lap and the accelerating braking that is going on. I try every time to keep my ca 80....100km/h, but most of the times I have to really slow down on the middle of the out lap to get the field together again as I allready open a gap on the second placed guy.
Once we got on the rew limmiter everybody should close up even more (each limmiter gets turned on later than the car infront by default). Once you see the car infront move you should immidiatly go for it. IMO the race itself dosent really suffer from the lack of T1 passes. Sure beats a classic mulit car off in the first corner which do happen even with a lot of care - it is extremly easy to brake a tad to late and than carnage happens. Especially in a mixed car field where some cars are far slower off the line even though they are faster on track - happens in the best of leauges (heck - even F1...)
