There are a LOT of long downhills here in Utah. I always bump the trans into manual and drop a gear or two going down. If I'm behind a "brake rider" who has the brakes on for miles, I can usually smell their white-hot brakes long before they get to the bottom. Can't help thinking their rotors have to warp from that.
My wife's Highlander Hybrid goes into Charge mode on downhills, of course, but she's a brake rider and I cannot get her to change. (Like most women, she understands the go and stop pedals, and that is all.)
