But really, it's good for either long or steep or both hills, but as far as I'm aware most autos let you select a lower gear so you can avoid over heating the brakes and because if you're braking down a hill unnecessarily you're just turning your fuel to heat and leaving the car in gear down a hill drives the engine without needing fuel and out of gear you're essentially idling so using fueland not in full control. I've only driven an auto a few times and found it a bit confusing at first, changing gear manually doesn't really involve thinking, even if I've not driven in months, kinda muscle memory.
The kinda muscle memory that has you reaching for the hand brake that isn't there 2 minutes after driving off in an unfamiliar hired car when perched at traffic lights on a steep hill.
