The too-slow roll when the first pop out of the elevator bugged me.

There's overrotation at play there, since they're rolling on rails. Basically the bearings are spinning on the rails at a "normal" speed, but each full rotation doesn't move them forward as much because they only touch the rails at the sides rather than at the bottom.

Too smooth. They're instantly at rail speed.
They'd pop out of the holes, and skid a bit as they'd decelerate. Then, since the rails are at a slight decline, they'd accelerate a bit.
