i agree with 2kool, for the most part, no drama.
But the high mountain passes here in Colorado are full of hairpin curves, switchbacks that drop down to 15mph, and some long open straight aways that are 40-65mph, then back into a 15mph curve.
trying to moderate between 15mph for a curve and 40mph for the straight away is gonna smoke those brakes fast. i've done it. i'm not a bad driver. it takes some practice to come down well. knowing the road and practice makes it safe.
i'm still alive so the buses are certainly forgiving.
we could have a few different classes in the downhill race: the 545's, the retarder's, and everyone else.
