             | decided that EVs should not be quieter than ICEVs, in fact
             | they should be _louder_. And some of the hybrids on the
             | roads (looking at you, Toyota) are the loudest of them all.
             | 
             | Different strategies for different cars, though.
             | 
             | My neighbor's Highlander hybrid is audible a couple blocks
             | away as it comes into the neighborhood.
             | 
             | Our old Bolt EV was not quite as loud, but still
             | distinctive and never a surprise to anyone as it came down
             | the street.
             | 
             | My Model 3, however, makes a white noise sound going
             | forward that you don't really notice aside from _very_ low
             | (single digit) speeds in a very quiet environment. But in
             | reverse, it howls pretty loudly, and is probably louder
             | than any of the hybrids.
