People aren’t hit by cars because they don’t hear them, they are hit because a driver is reckless. I was hit in the crosswalk of our lovely downtown, broke my leg, didn’t matter if the car made a noise or not. No, car noise is a public nuisance, a hazard far worse than any effects from the made up, drummed up hazard of people being hit by cars because they didn’t hear them! This is of course the argument that Harley Davidson drivers use to justify the hideous racket that they visit on the public, that they’re in danger if people don’t hear them. Auto manufacturers play up the idea of motor vehicles being tools of anger, aggression, of one upsmanship, of getting your own way regardless of its effect on others or the public at large. A big part of this is the sound they make, the cut out or after market muffler, or even the exhaust system that is allowed to become defective with age and not fixed. Loud noises, especially those of the low frequency and vibrating nature of these modified car exhaust noises that have in recent years become rampant on our roads, are harmful to people. They distract people, interfere with learning in adults and children, and foster an attitude of ill-will between people, a feeling of helplessness in the face of an unavoidable noxious stimulus. Lets join together and get these things off the road! Email me and we can start a citizens campaign!

These numbers are too small to be statistically significant and the NHTSA did not flag them as significant. Felix is making a claim that is not in the report and certainly is not justified by even a causal look at these out of context tables.

Maybe your ego will keep you afloat, your SUV certainly won’t.

Not that you care but actually you sound fake and arrogant very California. I’ll feel very bad the first time one of those little dumb cars bounces of my SUV…too bad the crazy’s driving them appear to have no driving or self preservation skills and insist on zipping in and out of traffic on highways as well as suburban streets where they have no business being in the first place. They were designed for the over crowded less affluent urban areas where people enjoy living on top of each other anyways…while pontificating with each other over 5 dollar cups of coffee solving all the world problems with other peoples money

We now have an opportunity to turn down the volume of modern society. People are going deaf and hence losing focus and the ability to concentrate and communicate. MP3 players, busy highways, televisions everywhere, muzak – society is damn noisy and just when technology gives us an opportunity to begin to appreciate some silence again – we start designing things to be loud. This is madness. If the collective ambient noise of everything was reduced, then we would still hear an electric car. It´s not the level of the noise of just one car, but the relative noise between all things. Let´s turn it all down as much as we can and restore some peace and quiet to the modern world.

“This study found that pedestrian and bicyclist crashes involving both HEVs and ICE vehicles commonly occurred on roadways, in zones with low speed limits, during daytime, and in clear weather, with higher incidence rates for HEVs when compared to ICE vehicles”

The idea that minivans and suvs arent around pedestrians and bicyclists as much as hybrids doesnt seem to be supported.

Sampled states are: Alabama, Florida, Georgia, Illinois, Kansas, Maryland, Michigan,New Mexico, North Carolina,
Pennsylvania, Washington, Wisconsin- so there is a pretty good mix there. Nothing to lead you to think that HEV are going to be over represented.

The most plausible effect is noise- cyclists generate a certain amount of ambient noise themselves and use motor noise to detect when vehicle are approaching. Absent enough motor noise to overcome the ambient noise, the cyclist wont be able to detect an approaching vehicle.

A rolling death machine?

As with any new technology, drivers and cyclists are going to have to adapt. Making them louder is simply stupid.

Statistically, any two populations can be compared without worry as long as their sample sizes are greater than 32. (That does not account for sample bias, but I don’t think that’s an issue here)
