This came up during the stress test and I realize it´s not particularly relevant in normal conditions, but it´s still a bug.

If theres a huge speed difference you often only see the blue flag message, by the time the lapping driver is already past you, like in a uf1/bf1 situation.

I also noticed this in one of the ukct servers with all slow cars. I was going slow because I braked late and noticed someone gaining up on me, but i didnt get a blue flag until he drove next to me.

Edit, maybe this had some other cause
