Via the Nissan LEAF blog - Nissan has unveiled the sound it’s Nissan LEAF electric car will make to warn pedestrians of its approach. Check out the vids below:
The blog calls is “the worst sound on earth” - I personally don’t think it’s all that bad. It’s fairly high frequency which will make it noticeable (and potentially more annoying at a given sound level) but on the other hand it should be easy to focus in the direction of travel and minimize wayside noise. I guess we’ll have to wait and see.
