Ah you're right, I overestimated drag vs. rolling resistance.

FWIW, Enterprise had a discount a few months ago on Tesla rentals, and I drove a Model S 70D up a fairly steep hill. The battery drained very very fast going up, with the miles remaining estimate going down something like 20 miles for only 4 miles covered, and then on the way down it barely gained any miles back.

Since the speeds involved were low, that tells you rolling resistance is still quite significant. That said, a permanent magnet motor powered car would probably do a little better on the same run.
