Going fast through turns is exactly the point for the majority of riders (all except choppers)
One of the reasons I stopped going on group rides was lead riders who burned through blind corners. I'll take an open corner with good visibility as fast as I dare, but if I can't see through the turn, I take it slowly.
Let the other guys arrive at the scene of the accident first.
You, me, a couple of other middle aged guys all hanging back on our sports tourers, while the crotch rockets are off antagonising the cage dwellers.
We'll all arrive in time for coffee, no sweat.
