Toyota Adds External Speakers To Warn Pedestrians
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."
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.
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.

The blind have no problems hearing electric cars.
They aren't deaf, like the rest of the retarded populace, and they don't have shitty white earbuds jammed into their ears 24/7, like the rest of the retarded populace.
Electric cars driving down a street are not quiet.
They are simply quieter than a regular car.
It's not like trying to listen to a cat sneaking up behind you on a carpeted floor.
