I'm kinda torn on this. I guess it is somewhat of a natural evolution as we take better care of the planet, but it is hard for me (probably cuz I'm old!) to let go of certain things. I have two old classic cars, and they make noise and smell; part of me tells me they are supposed to do this. They are uncomfortable, rattle, and have no AC. When I drive them they take me back to a different time when we didn't have all of the comforts (and maybe distractions) that vehicles have now.
Bikes are supposed to make noise to me. I am still coming to grips with quieter dirt bikes, but I am learning to appreciate them. One of my first mods to a bike in the past was to add a louder muffler; it was just what you did. Quieter bikes, and perhaps electric bikes, are probably something that I need to get used to.
Interesting to see where this goes. The trend of electric bicycles and scooters seems to be all the rage (although it seems that I read almost daily of someone getting hurt on one of these!) and I doubt it will pass anytime soon, if at all.
