It is unclear to me how everyone misses these points when discussing electric vehicles. My utopian view is electric bikes and electric velo-rickshaws in cities where heavy vehicles aren’t allowed (at least inside the living areas). Current road safety standards must account for collisions of heavy metal boxes moving at high speeds. Imagine how much less protection you need with vehicles weighing under 100kg and going at max speed of 25kmh. In a city like Berlin current average speed for cars is 17kmh. It is just stupid to keep going the way we do :'(
