So, since this is the digital 21st century and computer memory is inexpensive, what about this?
We all know there is the low tone noise built into the Leaf to alert visually impaired people (or those who can't walk without having their eyes glued to their cell phone). Why not let us choose what tone we'd like?
Nissan could include a number of choices, and people could create and upload their own (like ringtones). We could have Leafs whispering down the street to the sound of:
The Jetsons airship noise
Horse clip-clopping down a cobblestone street
Train going chugga-chugga-chugga
Rowers stroking in time to the beat ("Ramming speed" anyone...?)
The "Jaws" theme
I'm sure others could come up with even better suggestions...! I know, I know, this thread doesn't hold a candle to the arguments about locking EVSE cables and better navigation systems, but hey! Have fun with the car!
