Totally agree with the original poster, nicely summed up.
One other thing, too - it's related I think. A couple of nights ago, I saw a guy (who frequents the forums, and is quick) say some pretty ridiculous things to someone who was on the lead lap.
He seemed to think that because his lap times were faster, he deserved right-of-way, despite being at least a lap down... He proceeded to get up someone that HE crashed into! I just couldn't believe the arrogance...
If you're a lap down, don't race the leaders - even if you're quicker. If they're nice, and it's not a crucial part of the race for them, most will let you through... but they're under no obligation at all. Unless you can get past cleanly, without affecting their race, back off.
