Leelane Hines Posted over 1 year ago how can we make electric vehicles safe for pedestrians or others who cannot hear the engine? Noise pollution is certainly a consideration. Besides, if we all switch to electric cars the sound of hoof-beats would become commonplace thus counter productive for purposes of attracting a pedestrian's attention. Flashing lights are also pollution and distracting to all concerned. In the case of silent cars having the characteristic of sneaking up on us, are we stuck with people doing what they should do? Being careful?
