"Those of us who have been driving a Model S through the winter (I live in Colorado) applaud you for ‘telling it like it is’ without undue drama. Winter driving takes a toll on range for all vehicles, a toll that we often overlook when driving gas-powered cars with their imprecise, analog fuel gauges (and with a gas station on every corner).
A couple of observations: almost all of the loss of range at highway speeds is due to increased aerodynamic resistance, which increases as the square of velocity. Regenerative braking has nothing to do with it, as you implied in the article; in fact, hypermilers go out of their way to avoid regenerative braking because all regen can do is recapture a portion of the car’s kinetic energy, energy that was expended from the battery to get up to speed in the first place. Regen braking is a good thing, because otherwise you’d be throwing away all that energy in the form of heat generated by using the normal friction brakes, instead of putting some of it back in the battery pack; but it’s no perpetual motion machine."
