Traffic can ruin lap times, definitely. If I see a train of cars ahead of me, I will slow the car down a bit and then focus on perfecting my technique through the approaching corners. This way I don't feel like it was a total loss.

I have also seen some scary near-misses because people get bunched up waiting for the point-bys -- they start looking at the car that is causing the hold-up, taking their eyes off the car in front of them.
