and a high portion of freeway driving, which minimizes the opportunity for regenerative braking, are the most adverse conditions for any electric vehicle.
Alright, what am I missing? People Who Should Know keep making this strange claim that you get more energy from regenerative braking than not braking at all. I don't understand - when you're braking, you're only reclaiming energy you put there by accelerating in the first place.
I would have thought that freeway driving would be fairly ideal, since you're at a steady speed and basically only need to overcome air and rolling resistance, whereas if you're regularly using braking, you're also having to reaccelerate, plus you're losing energy in the form of heat and possibly sound.
I get the idea that adding regenerative brakes in the first place will increase your range, but I don't see why your range would be shorter because you don't get to brake. Am I missing something somewhere, or am I expecting too high a knowledge of physics in my car reviewers?
