i think pit lane traffic is more annoying, especially when you're in first say, with a 3-4 second lead, and second->tenth all come in at the same time, holding you up for 10+ seconds.
To be fair Nico it's a litlte bit too cautious at the moment. Sometimes you can get held up by two cars who on the track were running almost 2 seconds apart. Two seconds is more than enough for a safe release inbetween the two of them, afaik even 1 second is sometimes. Some of the cars in todays F1 are deemed as safe release and they are almost clipping bumpers.
Watch any race we have at Monaco. With no kers at the end of the race there is actually no hope of overtaking a backmarker who has his tyres at the right temperature at the point we meet. I was in the lead by 1.5s last night and then spent laps 75-77 behind a backmarker. We shouldn't have to wait until DRS to get any sort of chance, and all that does it just put us a little bit closer. They should just fully move out the way.
If youre able to overtake backmarkers easily then the standard in your league must be pretty bad.
