My point about needing ultralight vehicles is not mainly about efficiency loss when stepping on the brakes from a heavy vehicle. It's about the over complex, over sized, over expensive, over consuming of materials. We don't need vehicles that are this large and heavy and fool proof crash safe (expensive) to be able to get where we are going. The larger and heavier the vehicle, the larger the battery and motor that is needed to move it. We won't have enough battery raw materials to build 3 billion people a car with a 60kWh battery. And also build 100's of TWh's of stationary electrical storage. I am promoting a new way of thinking about enclosed, all weather electric personal transportation like the Electromechanica. But with 4 wheels for all weather use in the snow. Which right now is prohibited by law since it would then have to conform to all of the overprotective and wasteful crash safety. We need to learn to do more with less.
