Toyota Protecting Pedestrians By Making Prius Louder



Toyota has begun offering a speaker system to customers in Japan that makes a whirring sound similar in volume to buying levitra a regular car engine that will alert pedestrians of your quiet car's presence.  The device is available for the most recent generation Prius and will be offered for any new hybrids from Toyota going forward.  Drivers can buy the system for about the equivalent of $150.

The speaker was designed to protect pedestrians, especially blind pedestrians, who may not hear the car when it's traveling at low speeds and only running on the electric motor. The device will turn on every time the car starts, but can be turned off with a switch.

The U.S. auto safety agency found that hybrids were twice as likely to be involved in a pedestrian accident at low speeds than cars with conventional engines.

The Prius has been the buy cheapest levitra top selling car in Japan for over a year.  The popularity of the quiet hybrid vehicles led to a Japanese government report on the danger of silent cars and new guidelines that Toyota followed when developing the speaker system.

If quiet cars really are a hazard to pedestrians, it makes sense that this would be an added feature on hybrid or all-electric vehicles, so it seems strange that Toyota is offering it as a voluntary, paid option instead of just making it a standard feature.

Misleading safety claim: read the NHTSA report
written by Bob Wilson, September 10, 2010
The NHTSA safety report, DOT HS 811 204, can be downloaded from and does not claim "The U.S. auto safety agency found that hybrids were twice as likely to be involved in a pedestrian accident at low speeds than cars with conventional engines." Read the report and you'll find it is much narrower in its conclusions and suffers from a math trick.

The report in Table 6a, pp., 13, found "Making a turn," 19 incidents, and "Backing," 7 incidents had a slightly higher percentage of incidents than the gas equivalent car. Sad to say, these were not incidents divided by the number of cars in the 12 study states but just comparisons of fda approves cialis percentages. Even the report limits their conclusions to just "Making a turn" and "Backing."

In contrast, Table 3d shows hybrids are significantly safer in "Going straight" incidents, nearly 109 incidents avoided. Yet no one discusses the safer aspects of hybrids in "Going straight." The reason this is so traced to the math trick, comparing percentages of incidents, not rates of incidents per vehicle or vehicle mile. Let me give an example.

Take two identical pies and then manually cut them into eight pieces. Then measure all eight slices. If you find the northeast slice in one pie smaller in one pie, it is easy to claim,"this piece is smaller." But both pies still have the same amount and cialis tablets for sale other pieces will have larger. Don't mention the larger pieces and OUT OF CONTEXT claim "pie A has smaller pieces than pie B" and you've just been suckered in by the math trick this report pulls.

Read the source report, DOT HS 811 204, and check the usa viagra sales math. It does not claim 'hybrids are twice as dangerous' which by the way agrees with the NHTSA Fatality Analylsis Reporting System data.

Maybe not too relevant but: I've been a runner for many decades and often have to run on suburban roads without sidewalks. I always rely on listening to the noise made by car's TIRES, which, in most suburban venues is quite noticeable. Of course, I never use earphones. I prefer to listen to the birds (and the traffic...)
What about noise pollution?

Cars are loud and noisy. The noise pollution they create is obvious to soft cialis anyone attempting to hold a conversation on a busy road. Now we can finally limit this noise pollution. And instead we want to increase it instead? That is plain stupid.
Makes no sense

If the noise maker is only active when the car is moving and only below 5 or 10 mph it might the slightest bit of sense. Otherwise it is a waste of money and unneccesary weight added to the car

Can we at least record our own voices making car sounds? Vroom, vroom, vroom... I'd get in line for that.
