I pay to race.... I don't slow down, or move off my line for anybody.
IF you're good enough to lap me, you should be good enough to get around me. I certainly wouldn't tangle anybody up on purpose, and if I did and it was race leader I would actually let them go. IF they biff though, and end up behind me again they're gonna have to show how awesome they are and get around CLEANLY.
Because that's the other thing, I'm good enough to "punt" lapped traffic and I'm not that good... so again, letting people pass in a race is just ridiculous in my opinion.
I race real off road cars, and it's RARE that people just let you by. So, we bump em a few times and they usually move. Fear for your life will do that to you.
All of that being said, I've lost at least a few races due to lapped traffic. Do I get heated over it, sure, for about two minutes. It's RACING, and if you can't make a pass then you're not a very good racer. Turning fast laps with nobody on the track is easy.
