I need to mention a some stuff that I noticed while watching the race concerning lapping traffic.
I mostly saw good behaviour even though some lapped cars were being a little over zealous about trying to get out of the way.
I did see several cars, and I won't point out names here, that consistently held up faster cars for laps at a time. There were cases where the faster car was having trouble getting along side to make the pass. But, I could also see the faster car being held up in the corners and getting a bad launch off the corner and not being able to move alongside on the straight.
This is a two part problem. First, the faster driver needs to back off and work on his timing to leave the corner with enough speed to move alongside on the straight... or at least make it apparent that they are in position to move by.
Secondly, the lapped car needs to recognize when he is holding up another car. You may think you are maintaining a gap, but it is really an accordion and you are holding up faster traffic. Make provisions for this and although you shouldn't "roll over and die", be aware of good places to slow up for just a half second to let the faster car past.
I also saw on several occasions slower cars actively defending their position for several laps. At about the time I was going to recommend a warning or penalty, they would get passed, so no penalty during the race occurred. I actually saw several cars chop down on lapping traffic actually causing contact in mid corner.
All I can say about that is to pay attention. The corners are the best place to make a solid pass happen that does not cost much time to either driver. Be aware and know where the other car is. The lapping car must be aware and in position to take advantage when a lapped car "squares up" a corner so that you can get by. But also be aware that some corners are not good places to quickly get by. You must respect the race of the lapped cars too.
If lapped cars continue to fight faster traffic, it will not be good for any of us. It will lead to more contact (potentially semi-intentionally out of frustration) and more wrecked cars. It will make our jobs as Admins more difficult and time consuming.
We all know that the LFS blue flag system is not perfect. You must rely on your team to keep you informed on where each car behind you is in the standings and if you are fighting them for position or to perhaps keep from getting lapped. If not, work with the lapping traffic to make the pass happen where it costs both of you the least time. Remember, .1 second lost letting a lapping car past is much better than getting punted after holding that car up for 3 laps. It would hopefully be unintentional punting, but even if it isn't and the other car gets a penalty, you still got punted and had to pit for repairs or get pulled out of the sand. Not good for anybody.
