Toyota Adds External Speakers To Warn Pedestrians 531

HockeyPuck writes "When I was a kid, playing with my matchbox cars, I used to say 'VROOOM VROOOM' to pretend my toy cars had big engines in them. Well it seems that Toyota has decided to do the same thing with the Prius by optionally installing, in Japan, external speakers to alert pedestrians of oncoming Priuses."

      No. Think about a (hehe) child (hell or even a Santax) playing between some cars. It is silent, I can hear nothing. I assume (since I know when I hear nothing there are no cars) I can safely cross the street. Only to Die by Prius. This really is one of the biggest disadvantages of these types of cars. You can't hear them, so your brain isn't in the alerted modus. If every car we have today would be silent you would see a great increase in traffic-deaths. So for me this worth applauding.

        For most vehicles travelling at around 30km/h or more, unless the driver is standing on the gas pedal, most of the noise comes from the tires, not the engine.

          So you propose we introduce traffic laws that require cars to at all times be going above 30 km/h?

            Well, interestingly that under 30 km/h, my fan and/or AC compressor is louder then the engine too. Those would still exist on electric cars too, you know.

        • Right. Which is why the study linked into the article states that the major increase in accidents with pedestrians and hybrids occurs at very low speeds, especially backing up, parking, and pulling out into traffic.

          Read the study, it's good stuff. I admit, I was sort of dubious of the threat posed by quieter cars, but the study is reasonably convincing that at least at slow speeds, it's a problem.

            Indeed, read the study. I am even more dubious of the threat posed by quieter cars. The sample size of hybrid accidents with cyclists and pedestrians is 125. 125 incidents for HEVs versus 5440 similar incidents in ICE vehicles. The study controls are also *very* dubious. For ICE cars they analyze the Camry, Corolla, Civic, and Accord. For HEVs they compare with the Camry Corolla, Civic, Accord, *and* Prius - a car with a fairly novel design and different viewability than you find in the more "standard" sedans. I'd be very curious to see how the number line up without including the Prius, but seriously doubt there will be enough data to prove anything conclusive.

            So yes, I am extremely dubious about the threat of "quiet cars," thinking it is often being used as an excuse in place of an actual cause (say... driver or pedestrian inattention?). Sure, some tech-gadgets really do save lives, but too many new "safety and convenience features" on cars simply encourage lazy drivers.

          They put low rolling resistance tires on a lot of hybrids to pad the MPG numbers. It totally compromises the handling and safety of the car but all they care about is the MPG they get to advertise. Those tires make almost no noise at all.
          • You know, I had those tires in my Civic. I had little handling issues with them in Colorado and they certainly made a fair amount of noise on the road. The only reason I didn't replace them with another set when they wore down was basically cost. I haven't noticed any difference in the handling in rotten conditions (admittedly, I've also moved to a snowier place), to be honest.

            Certainly, the average experience may differ. Do you have any studies that show that said tires result in a statistically signif

        what? From the age I was allowed to cross the street, I was told to LOOK both ways, never to just listen for a car. There are many things that move that don't make loud engine noises (bikers, runners, segways, animals) AND fast moving cars. If a car is moving fast enough, you won't hear is coming [till it is too late], especially in a traffic filled area, there are always car sounds. you _ have _ to _ look.

        If you consider the quiet of the prius to be a disadvantage, then roll down the window and just scream the whole time.

        The only reason this would be useful for is blind people. The only [legally] blind person I've even known, only walked in neighborhoods (where cars should be going slow enough to yield to any pedestrian) and cross walks (that have an auditory signal). No where is car sound reliable enough to be a decision making factor.

        No, if every car on the road was as silent as electric cars are people would not learn to rely on their hearing to check for the presence of cars. They would look for them instead, just like you're supposed to do now but often ignore 'because you don't hear any cars coming'.

        Assuming they push the pedal to the floor during the heart attack and rigor mortis kicks in immediately, the gas engine would kick in and produce noise. Otherwise, their leg muscles would relax once they die making it near impossible for them to push the gas pedal.

      No. Unless you routinely honk your horn while coming around blind corners (note: this is actually required by law in most states but nobody does it).
    • Isn't that what the horn is for?

      That's to lean on with full might at the last minute while applying screeching brakes attempting to kill the pedestrian of regular heart attack, while claiming full innocence. Lawyerly weaponry. Especially if you upgraded to those trucklike horns that make the entire neighborhood know you just killed a another lady with the heart attack braking technique.

      I was nearly taken out by an effin hybrid car once (a Ford Escape) running under battery. There's no way to hear those coming in a city noise background.

        To be fair, Toyota is crippling it in one market, optionally, by the owner's choice. That's very different than a state requirement that must be met.

        Of course, I've always wanted an option that wasn't quite horn, but wasn't just sitting-politely-waiting either. Keep the horn for the "Oh God We're All Going To Die" moments, and have some sort of sub-horn for "The light turned green: stop texting and drive" or "No really, we're in a right-turn-on-red state."

        If we could hook the outside speaker up to a microphone on the dashboard, I'd be happy. Well, I'd be angry, and there would be a string of expletives that came out of it. But it would be satisfying.

      While I agree that adding noise to a car is counter-intuitive, I know that at least one group, representing those who are blind, has complained about the lack of audio cues of an oncoming hybrid vehicle. This was part of a news program that I was watching at least six years ago. It's not just idiots who are not paying attention that are complaining. There are others, with more legitimate complaints, who are complaining as well.
      • And for those with legitimate complaints, such as the blind, I can sympathize. I just find it really hard to believe that adding more noise to a car is really the best solution.
      • I daresay the idiots not paying attention are the drivers - because if they were, they wouldn't be mowing down passengers [by accident].
    • you could fix the noise by using one of those Military Pain guns instead. That should get their attention.

    Camera alternates between showing the closeup of the girl and showing the empty road.

    Screen goes black and in a short while there is a loud noise as if someone was hit by a car.

    The following appears on screen: "New Audi type foo. Very fast. Very quiet."
