Nissan Gives Electric Cars Blade Runner Audio Effect
mateuscb writes "A campaign backed by automakers and some lawmakers to make electric or hybrid cars noisier in a bid to increase safety for pedestrians and cyclists has taken a strange, Blade Runner-type twist. Nissan sound engineers have announced that the Leaf electric car set for release next year will emit a 'beautiful and futuristic' noise similar to the sound of flying cars — or 'spinners' — that buzz around 2019 Los Angeles in Ridley Scott's dystopian thriller based on a Philip K. Dick science fiction novel."
The Doppler Effect should take care of that for you. No matter what kind of sound is made, it's affected by the Doppler Effect.
"..."
According to the article, the sound is supposed to turn off after the car reaches 12 mph because at that point they say the tire noise is enough to let you be able to hear it adequately.
My other sig is an import.
An example of the sound is apparently this one. Not sure tho', found on an another site.
But at TFS says, it's a 'safety feature', I'd imagine you could 'turn it off' about as easily as the airbags or that thing that beeps when you're in reverse, and that's not without messing with wiring.

These proposals are just as idiotic.
It's the drivers' responsibility to maintain control of their vehicles and be cognizant of sudden dangers in the street. Any attempts delegate this responsibility onto pedestrians, wildlife, and falling trees are completely retarded.

Contrary to popular belief, life is not a bitch. It is far far worse.
I'm willing to bet the wheels on pavement are enough of a sound for someone who is constantly using hearing to find out what is going on around them.
I had the experience of being sneaked up on by a Prius on in a narrow street last year. The ground was very clean (none of the loose salt/sand that is often on the roads in the northeast) and its gas engine must have been off-- that vehicle was absolutely silent. I gained an appreciation for the issue of lack of vehicle noise that day. Perhaps at 60mph tires make a noise, but at the low speeds on streets they aren't always discernible.
There's a perfect xkcd for my sig but I'm too lazy to look it up. sudo someone go find it.
Your eyes aren't everything - I don't know about the rest of you, but I'm much faster to react to something I hear over something I see.
I live in a fairly large city in the northeast US. I walk a lot, but not like true urban walking - it's a mile and a half to the train station, and I walk it twice a day outside of light groceries and the like. I grew up walking in NYC and its suburbs, and I've been lucky enough to never actually need a driver's license. My feet do me just fine for most things.
So believe me when I say that the idea of a truly silent car terrifies me. I look both ways when I cross the street, I don't habitually jaywalk, I follow street signs and stay on the curb until the light changes, but if all that fails or if a driver isn't paying the same kind of attention I am to the road (he has a steel cage around him; I don't) I rely on my ears. I've had my ass saved on more than one occasion by hearing a car swinging around a corner towards me that I couldn't see yet.
There are a lot of stupid drivers on the road. There are also a lot of careless or over-confident pedestrians. But I can't see this as a bad thing - my eyes might keep me from walking out into the middle of traffic, but my ears are what get me to step back quickly onto the curb because somebody in a car isn't being careful.
Do pedestrians really always have the right of way in the US?
There are no national traffic enforcement laws in the US; each individual state sets their own. The national government only provides financial incentives for the states' laws to meet certain criteria.
Pedestrian right-of-way laws vary considerably across the country and are a dissonant mix of historic inertia and regional practicality. In Boston or New Orleans, jaywalking is common and pedestrians routinely cross streets where and when they choose. The local courts will invariably find the driver at fault. In Washington DC or New York, jaywalking laws are actually enforced. In Salt Lake City or San Diego, jaywalking is extremely rare and drivers are given more leniency in the courts.
A few things are fairly universal:
-For the most part, pedestrians have the absolute right-of-way, anytime and anywhere.
-If you hit somebody near a school, a playground, or a school bus, you will always be at fault, under the assumption that you were driving too fast to stop for a child.
-If the pedestrian is actually trying to be hit (i.e. suicide attempt/insurance fraud...not just crossing recklessly), the driver is generally not liable.
-Striking a pedestrian on a limited access highway where they are not allowed will usually result in both parties being held responsible.
As a foreigner driving in the US, don't make any assumptions about pedestrian rights-of-way until you are familiar with the local laws.
