It's true that it's not a huge savings, but there's some savings. The EPA estimates approximately 1% reduction in fuel economy for each 100lbs added, so you might get a few % from the the battery weight savings.

Sure, for fuel economy, presumably without regenerative braking. When you're not in smooth traffic, a whole bunch of energy is lost in braking, and that energy is directly proportional to mass.
