Fake Car Noises Being Added To Many New Cars... May Be Required Soon
from the vroom-vroom dept
Last year, we pointed out that some car companies were experimenting with adding fake engine noises to their cars, after complaints were heard that hybrid and electric vehicles were "too quiet" and sneaking up on people. Apparently, those original experiments are turning into a groundswell. After some politicians decided to put forth legislation requiring such sounds, apparently lots of car companies are adding sounds to their cars, such as Nissan's recently announced plan to include futuristic Blade Runner-style sounds. Reading through that NY Times article, it seems like the car companies are less concerned about the safety issues, but are excited about the idea of opening up a new market for selling "car tones" -- like ringtones, but for your car noise. Can't we just set it to vibrate? In the meantime, there appears to be no evidence that these hybrid and electric "menaces" are causing any more accidents in their "silent, but deadly" current state.Thank you for reading this Techdirt post.

Jimmy Nosight turned in his general direction, looking vaguely lost, and sputtered, "B-but, please sir, how will I be able to know where the cars are when I can't see them coming?"
Brian leaned back and barked out an evil laugh before rearing back and bringing his fist down upon Jimmy Nosight's crown. Jimmy crumpled into a heap at Brian's feet, leaving him free to stomp his head until grey matter oozed from the poor blind man's lifeless carcass.
"Problem solved, blindy," Brian spat. He returned to his car and peeled away, the theme song to Hawaii Five-Oh blaring from his speakers.

That sarcastic remark only mirrors the idiots who vote against any sort of noise in a car, be it a futuristic sound or a fake engine noise. People complain about the requirement for seatbelts.

Hell, I've even heard someone yell out of their window at the sheer audacity of having a 15 mph school zone outside of a freaking school.
Noise of some kind *should* be put on cars and any attempt at removing it should be met with the harshest penalties possible.

i think the problem right now is that given more then one vehicle on the road if one of them is electric you cant hear it because the rest of them drown out its noise but once we get to only electrc vehicles we will hear them all.
however if we legislate noise devices for these cars then the noise will need to be as loud as the curent noise level. this will lead us to the day when we all have electric cars but still the same level of noise polution

I walk to work. Across fast secondary, and slow quiet subdivision roads and through even slower workplace parking lots.
Engines on a modern family sedan contribute little to hearing a car coming toward you. That is mainly wind tire noise. You hear the engine sound as it is driving AWAY from you.
In most parking lot setting you will hardly hear anything as engines are idling and ambient noise will cover that. I have had numerous people walk in front of my car in parking lot settings. The onus is on the driver to pay attention and not run into people.
In short completely useless idea, trying to solve a problem that doesn't exist, by making more unwanted nuisance noise.

"Federal researchers who examined 8,387 hybrid and 559,703 internal combustion engine vehicle crashes in 12 states, including Florida, discovered the incidents commonly occurred at low speeds, when the sound difference between a hybrid and traditional car engine is the greatest. But accident rates with pedestrians and bicyclists were almost the same for both engine styles when the autos were going straight.
None of the accidents studied were fatal."
This is clearly an area that legislators should get involved in immediately. Much time, effort, and taxpayer money must be spent now if we are to start saving these zero lives as soon as possible.

Anti-tax people really need to open up their mind about what constitutes a tax or subsidy. Any time government sets up anything that favors one industry over another (corn over broccoli, cars over trains), or rests power in a privately held Trust or Monopoly (insurance, autos, telcos, cable, etc.), you are being taxed by those corporations via a combination of direct subsidies and monopoly rents. Those taxes probably amount to more than the ones the IRS deals in.

US Pedestrians
I've been living in the US for a year. The ignorance of the average pedestrian is amazing. People will routinely step out into the road without giving the slightest thought that a car might be bearing down on them. This is also reflected in the rules which says a car can not overtake a school bus on wither side of the road as a child may run out. They should be taught to respect the road, as it's deadly.
So, with respect to noises on electric cars - don't get me wrong, it's a geeks wet dream to have knightrider noises etc - the burden should be put on the pedestrian to check that the road is clear.
It's basic Darwinism in action.
[ link to this | view in thread ]
I think the relative lack of engine noise almost certainly contributed to this, although it's probably something I could get used to.
I think more noise in general could be helpful for things like cars backing out of driveways (or even going forward out of them), although I suppose I should be careful what I wish for: the backing truck beeps are really annoyingly loud and high-pitched.
As for money, I'm sure it just costs a few extra dollars to to put in these speakers and whatnot, which, compared to the price of a car, is practically nothing. The question should just be whether this is a good idea in the first place, not the role silly sound effects will play in the car commercials of the future.

Re: No Evidence...That Mike Bothered to Look For
Too bad you didn't actually read those articles after you found them. A couple of good quotes:
"But accident rates with pedestrians and bicyclists were almost the same for both engine styles when the autos were going straight." (Sun-Sentinal article)
"None of the accidents studied were fatal." (Sun-Sentinal article)
"There was no statistically significant difference in incident rate of pedestrian crashes involving HEVs when compared to ICE vehicles when both type of vehicles were going straight." (US Dept of Transportation study)
Also, after looking at the actual data in the US Dept of Transportation study, the difference in accident rates in low-speed and turning collisions (the only category where there was any statistically significant difference) was actually much less than the "double" figure in the headline of the Sun-sentinal article.
There may also be an issue with the sample size in the study, which appears to be quite small. (Only 75 Accidents involving Hybrids were used in the analysis).
Plus, the last time I checked, when a driver is involved with an accident with a Pedestrian or Bicyclist it is assumed that the driver is at fault unless proven otherwise. This means that it is the drivers responsibility not to run into people. I also remember from drivers training class being instructed to be extra careful whenever you see a blind pedestrian (identified by a walking cane or seeing eye dog). There are also lots of silent and near silent vehicles on the roads: ever been to Florida or Palm springs? You can drive Golf Carts on the roads there, which are silent and can go pretty fast, and they don't seem to cause havok. When going downhill or on very smooth streets I will often shift my car into neutral. It becomes nearly silent when I do so, yet no pedestrian (blind or fully sighted) has ever stumbled into my car because of it. It is not the vehicle manufacturers responsibility to ensure that their vehicles are loud.

Perhaps, if we quit letting people get away with stupidity, we'd have less stupidity? Best intersections I've seen in cities: one direction goes, then other direction goes, then all pedestrian traffic goes. Never a conflict between drivers and pedestrians. Simple and much safer than noisy cars. What do you do with hearing impaired people? Or people jacked into their music players? Or distracted people?

Re: Re: Re: No Evidence...That Mike Bothered to Look For
Ok well let's look at the evidence you presented. The Sun-Sentinel article was based on the Department of Transportation study (and also has a misleading, fear-mongering title). So the Sun-Sentinel is not in itself evidence, but simply a reference to the study done by the Department of Transportation. The Department of Transportation study is based on 77 incidents involving Hybrid vehicles, vs 3,519 incidents involving Non-Hybrid vehicles. The "double" number referred to in the article's headline is taken from the low speed incident data in which shows incident rates as follows (incidence rate is a measure of percentage of vehicles on the road that will be involved in an incident in the studied time period):
Going Straight: Hybrid 0.9%, Non-Hybrid 0.8%
Making a turn: Hybrid 1.8%, Non-Hybrid 1.0%
Slowing/Stopping: Hybrid 0.5%, Non-Hybrid 0.2%
Backing: Hybrid 5.3%, Non-Hybrid 2.9%
Entering/leaving parking: Hybrid 1.2%, Non-Hybrid 0.9%
Starting in traffic: Hybrid 2.9%, Non-Hybrid 1.2%
Other: Hybrid 0.3%, Non-Hybrid 0.2%
At first glance it appears that the hybrid vehicles are involved in a higher rate of incidents. But the flaw is that due to the small sample size (remember, only 77 incidents involving Hybrids were used in the study) the confidence interval becomes a whopping +/- 3% for the Hybrids. The confidence interval for the non-hybrid incidents is a much more reasonable +/-0.3% due to a much larger sample size of non-hybrid incidents. That means, for example, that the 5.3% number for "backing" may actually be as low as 2.3% or as high as 8.3%. The confidence interval of 3% for the Hybrids is larger than the any of the differences involved, so the differences are not actually statistically significant due to the small sample size. The study does make claims of statistical significance, but the calculations for statistical significance that they used appear to be based on only the total number of vehicles studied, and are therefore flawed. As a result, the Department of Transportation Study cannot actually be viewed as evidence either. A new study would have to be conducted with a much larger sampling of incidents involving Hybrids before any real conclusions could be drawn.
So, no your examples still do not offer any evidence that the lower noise levels in Hybrids cause more pedestrian accidents.
Even if conclusions could be drawn from this study(which they can't), why would that actually warrant a mandatory loudening of Hybrids?

Isn't that what Canada did adding a tax to blank CDs and DVDs and sending the payments to the music industry? It's hardware, and since it exists, it's 'obvious' that users are going to use it solely for 'piracy' (or so they say). So why not tax ultra loud hardware like they do media hardware?

Re: Re: Re: Pedestrian safety enhancement act
Instead of the horses head thing, this reminds me of having a man with a red flag walk in front of the car to warn pedestrians. Pointlessly removing one of the advantages of a new technology. Next people will be legislating to stop people taking advantage of the free distribution available on the internet! Oh, wait ...
There are plenty of solutions for allowing blind people to cross the road - starting with traffic lights with beeps (after all, isn't jaywalking already a crime in some states?) and moving on to guide dogs, plus whatever the future can come up with - personal radar?

Okay, next time, I'll make a "vroom-vroom" sound.
Oh, and I, for one, never called for federal action. I just said that the technical solution isn't a bad one.

Re: Re: Re: Re: No Evidence...That Mike Bothered to Look For
But I disagree that this can't be used as evidence that quiet hybrids aren't a greater danger to pedestrians and cyclists. We can argue how much more of a danger, and if so what solutions might be undertaken to mitigate that danger, but I still think Mike's claim that there is no evidence is false. If he'd taken the study into account and dismissed it as you have, he would have at least been more accurate (though I might still disagree).
And, for the record, I don't think that a "mandatory loudening" of hybrids is warranted. However, if car manufacturers want to provide it, I also don't seem much wrong in that.

So you want to use statistically insignificant data as evidence? Well, ignorance is as ignorance does.

Re: Pedestrian safety enhancement act
coming at me at about 25 m/h (My estimate). I was hit on my right thigh, thrown onto the pavement, suffered a compound fracture of my left elbow,numerous bruises and lacerations and it ripprd a piece of bone out of my elbow for which I just had bone graft surgery. Five days in the hospital, 3 weeks in skilled nursing and have to wear a heavy metal brace 24 h/d. I never would have been hit if I had heard the golf cart coming.
Administration and residents (About half drive golf carts) don't want any change: No crosswalks, no speed bumps, no manually operated stop signs, and no sound from their carts.
If you get hit like I was, you will change your mind.
