My wife got a loaner 2012 Lexus hybrid for the day and she noticed the "growling" sound it makes when running in EV mode and backing up. The service advisor made a point of mentioning it to her, saying the car had to emit sound to be 'heard' by people nearby. I know this concept has been discussed before with the Model-S, but anybody "heard" (sorry) more about whether this was a homologation requirement?
