Yes I think the noise makers could be directionally forward. If sounds were standardized in their frequency then sensors could be developed that would listen for that noice and alert blind and deaf people / even cyclists to the fact there was a car approaching. You could even code the speed and left / right turn signals into the noise so the sensor could tell the person carrying it something about the approaching car.
I do think beepers for backing and turning is useful but agree they should be able to be silenced at night / maybe after 8pm? or manually or ? at least for non commercial vehicles. > On Nov 15, 2016, at 12:56, Cor van de Water via EV <ev@lists.evdl.org> wrote: > > Hi Thos, > Yep, early Leafs have noise maker that can be canceled (but just like the > communication warning, returns after the next time starting). > I believe this was so that the vehicle can be sold in countries where a noise > maker is allowed (or required) but needs to be muted at night. > > The blind person argument you describe is set in dead silence, the city > street situation is set in a surrounding with a lot of other noises masking > the quiet sound of slow rolling tires. > There are plenty reports about this and while it is possible for an attentive > person in a quiet street to hear all traffic approaching (I actually rely on > this when I am riding my bike) it is not possible to depend on this in > noisier environments and that is where the noise maker comes in. > Note that the noise maker is not making a lot of noise, it is not your > neighborhood jacked pickup truck that everybody recognises from waking them > while they sleep, it is just a small hiss as if the tire has a leak.
