I think with hilly areas having regenerative breaking helps as you can regain some of the loss on the way down.

  Regen is fairly common with direct-drive hubs, but it's not beneficial for range. You get something like 5% more range on a hilly route. The vast majority of energy goes to drag unless you're puttering along at 10mph. It is very useful, but more for saving brake wear.
