When I drive my ICE now, I do a lot of covering the brake...particularly on the highway, when someone will pull into my lane directly in front of me, cutting my following distance to near zero. In that situation, I don't want to touch the brakes (being on the highway), but my following distance gets cut short so I cover the brake to be ready to stop at a moment's notice. I just realized that doing this in the Roadster is not possible (short of using 2 feet, which is a no-no). Doing it in the Model S probably will not be possible either. Well, it's possible, but (even if a regen "deadband" exists) would cause heavy regen and brake lights to kick in. So: the technique of covering the brake rather than braking, which is a way of improving efficiency in an ICE, actually decreases efficiency in the Tesla's regen/braking system (some losses in regen vs. just coasting). Just an observation. Any Roadster owners have comments about not being able to efficiently cover the brake anymore?
