The news today is that from tomorrow, new Electric Vehicles will be required to make suitable warning noises at low speeds to alert pedestrians and cyclists of their approach. This will be provided via loudspeakers mounted front and rear for forward and revers motion use. Although the driver will be able to silence the sounds, it will be there by default (so will reset to on when the vehicle is restarted). I remember a few years ago when the law was passed and wondered if this would start an after-sales market for custom sounds. I can just imagine somebody wanting to change their reserved but perfectly adequate Fiesta sound for that of a V8 muscle car, or for an F1 racer scream (pre current silencer rules). Maybe there is an opportunity to have a more abstract sound like a clattery diesel, a clip from Kraftwerk's Autobahn, horses from walk, through canter to gallop, or even a Desiro spaceship tone. Any views here?
