If you receive the blue flag, say coming out of T1 at Blackwood, and have made no effort to relinquish position to a faster car behind you by the time you reach the turn at the end of that long straight - you have little common sense, or racing sense.
Yes you might have to slow, as everyone is pretty fast on a straight, but there is no better place to let the pass occur, and you will definatly hold the person behind you up in the turn(s) ahead, and possibly end up causing both of you to crash.
On the other hand, same situation, but the slower car in front is battling another car directly in front of him for position, and I'm the faster car at the very back - I accept that there is a battle in front of me, and the only way I'm getting around is by some miracle / mistake , or incredible draft.
I can't expect them to stop their battle. It's going to be tricky to get by them, and I could lose a position because of this.
THATS racing. You can't always get around slower cars because you 'need' to. On the other hand, there is NO reason for a single slow car to hold up any faster car.
What is bewildering is the mid race joiners, who are several laps down and make no effort to relinquish a position, despite the fact that every other person on the track is well ahead, so it doesn't matter who's on their bumper, they are legitimately needing to get by.
I suspect that people not responding quickly ( or at all ) to Blue Flag messages have often not been in the position of being in front of a race for 90% of it, only to have it ruined by a slower driver with a blatant lack of common sense.
