The move to include sounds is largely targeted at those who are blind or visually impaired.

Hoof Beats? Really? At 15 MPH or less? If Mercedes-Benz can make sensors that allow a vehicle to stop short of a vehicle stopped or to maintain distance during cruising, why can't the same sensor array be used to flash headlights or the audible double honk warning prior to the vehicle stopping on it's own. For that matter, how about day/night vision that compares digitally comparative movement from outside of the planned vehicle path based upon steering position.  Making noise to prevent accidents is like putting playing cards into the spokes of my bicycle, it might keep those with hearing out of the way, but what about grandma or the late night pub crawler?

Thanks, EdV, that gave me a laugh. I think the sound of horses' hooves would be a vast improvement over many city sounds.

Thanks Ann. Actually, I was not kidding. :) I think it would improve the acoustic background of most places, especially Manhattan, where the background is "siren".

I agree, Ann. Joke or not, I think it's a great idea. I don't know anyone who doesn't think that the clip-clop is a pleasant, soothing sound.

I like the clip-clop of horse's hooves as the sound--maybe Ed was joking, but I think it's a great idea.

EVs to be Noisier

  I can certainly understand the need for this.  I have an issue with hearing and EVs, depending upon the model, are almost "nonexistant" when unseen.    In the work I do on a daily basis; i.e. gas combustion, its'a know fact that natural gas is oderless so, an oderant is added for detection.  Very same principal as Charles has mentioned.  The automakers are definitely following the logical path, even if my mandate.

Endlessly playing the instrumental version of the classic "Spanish Fly."

 All joking aside, I think this is a good idea. If only to protect the blind and telling the driver their car is actually on. Sometimes EVs sound like they are off at stoplights.

Excellent sound choice!  I want mine to sound like a pair of horses on cobblestone, with the gait matching the vehicle speed.

Believe it or not, oldpartsnrust, there was a movie called "The Dilemma" with Vince Vaughn where the main characters do the very thing you've described. They develop a way to make an electric car sound exactly like an old-fashioned muscle car.
