If I had an electric car, I would want the sound effects of a top fuel dragster for acceleration, but a steam locomotive for cruising.
Decades ago in Zermatt, Switzerland, they required all electric for vehicles due to the smog in the closed valley. After hitting many pedestrians with electric cars and buses none heard coming, they added the requirement of sleigh bells.
Sleigh bells??? Lol. I have a Corvette. It sounds pretty nice to me :)
