I got this one, with a safety shutdown - three times in less than a block, going down a rather steep hill in Seattle on a full charge - one hour after unplugging.

I guessing it's the Seg's way of saying that the hill is so steep that even forcing you to slow down isn't enough to prevent overcharging.

Getting a shutdown on a steep hill is frustrating. It's difficult to restart and find level when the Seg is trying to roll away.
