I have raced this server a few times over the last few days, and I have to say that it's very enjoyable racing.
Yeah, there are occasional crashes, and most of the time they are in turn one, but what would you expect? 25 or more cars, all having a long run in to T1, braking from 150mph to 108mph within 20 yards, and all trying to navigate without touching anyone - that's part of what makes it such a challenge.
I've not experienced intentional crashers - every race replay is watched, and 9/10 times crashes happened because of the volume of traffic in a single corner. That's racing and if you cry about it, then go play mario kart instead
