I was initially opposed to proposals to make electric or electric/fuel hybrid vehicles make more noise. Isn’t one of the benefits of these vehicles that our neighborhoods are less noisy? But I guess people are concerned about the possibility of accidental death and dismemberment (?!?!?!?). All of my concerns are addressed in this excellent press release and video from Toyota for their new noisifier system. Not only does it sound super futuristic, you can turn it off if you need to murder someone!
