Backing on hills also took advantage of reverse being a lower ratio. In Signal Hill (~ Long Beach), CA there used to be an event for this, a Model T Hill Climb.
It's thought of as only one like it in the US. There's plenty of onlookers, local news coverage, and repeat participants. There is one specific hill but several that approach from different routes.
Driving a regular car on it, either direction, is not enjoyable for the faint of heart. With motorcycles being gravity fed, I avoided climbing some of them, definitely. Something about lower gears, higher RPM's, and a paper medicine cup sized float bowl.
