I'm very familiar with what you're describing, yeager
There are probably just as many T1 flops as there ever were. Perhaps there are a few less.. CTRA does filter out some right malicious idiots. The major difference now is that you're no longer involved in the T1s. What's happening is that, as you're gaining more experience, you're placing your car in a better place on the track. You're also seeing and anticipating other peoples' mistakes, and avoiding them in time to avert an accident. Whereas once upon a time, someone else goofing would have inevitably led to you suffering - often in T1 - it isn't the case any more.
The barf incident the other day is probably as much to do with how your expectations of others has increased as you yourself have settled in to LFS, learned the intricacies of car control, and seen the errors others make more plainly. I suspect the whole matter can actually be viewed entirely in a positive light.
(apart from the arguing in the servers.. that's still not okay
)
