I had noticed that I never roll backwards on hills after lifting my foot off the brake (no brakehold activated). This morning I decided to test that on the steepest hill in town. I went halfway up the hill and took my foot off the Go pedal. It rolled slowly to a stop and then started rolling backwards (that, I didn't expect) so I hit the brakes to stop. Surprisingly, when I lifted my foot off the brake, it did not roll backwards at all. I want to emphasize this is without brakehold activated. Thus, the Clarity is programmed to be very safe on hills. Just remember to apply the brakes normally as you would on any other car.
