Public-Racing can be a pain in every racing-game.
But the biggest problems are on servers with:
Cars: GTR´s
Track: As-National
Qualy: no
Laps: 5
join Midrace: yes
If you wanna better racing, search for servers with better settings.
And find a league, that fit to you.
Special in the smaller leagues, you find better racing. Ppl know each other, and respect each other.
Even many teams have own challanges, and they only allow ppl, they saw racing, and saw they are fair racers, who break before they crash another driver.
Much written in bad english, and all i wanna say is:
Stay away from the public-servers, and you will get more fun and less trouble.
