Hybrids Safer In Crashes — Except For Pedestrians

Posted by timothy on from the downloadable-cartones-soon-enough dept.

Hugh Pickens writes writes "Hybrid vehicles are safer than their conventional counterparts when it comes to shielding their occupants from injuries in crashes with the odds of being injured in a crash 25 percent lower for people in hybrids than people traveling in comparable non-hybrid vehicles. "Weight is a big factor," says Matt Moore, of the Highway Loss Data Institute. 'Hybrids on average are 10 percent heavier than their standard counterparts. This extra mass gives them an advantage in crashes that their conventional twins don't have.' The study's findings are good news for green-minded drivers who are also looking for safety in their cars, but it's worth noting that hybrid vehicles are much quieter than gas-powered cars, posing a risk to pedestrians. "When hybrids operate in electric-only mode, pedestrians can't hear them approaching," says Moore. Earlier this year, Congress gave the National Highway Traffic Safety Administration three years to come up with a requirement for equipping hybrids and electric models with sounds to alert unsuspecting pedestrians."

      You don't seem to know a lot about reducing the risk of injury to a normal human being. Unfortunately our senses are not perfect, sometimes we miss things or are distracted and forget to look. Audio cues help prevent mistakes turning into accidents and have been shown to be very effective. Emergency vehicle sirens, for example, have been improved so that they give drivers some idea of the direction the vehicle is approaching from.

      The problem with EVs isn't as bad as some people make out though since much of the noise is from the tyres on the road and air being forced aside; the engine contributes relatively little. We have an opportunity here to develop sounds that make people take notice rather than the default noise a petrol engine makes, and the person inside the car need not hear it.

      In traffic, maybe. But I don't think this is necessarily about people crossing at the light at a crosswalk at a busy intersection.

      I live in a city, where there's a lot of ambient noise. That city is San Francisco, where, as you can imagine, there are a lot of hybrid cars. And I can tell you, while not being elevated in my mind quite to the level of "cause for concern" just yet, quiet cars can be a problem.

      I live on a predominantly residential street, where people have their cars in garages with very short driveways that cross the public sidewalk. The sound a combustion engine makes when it's backing out of a garage at low speed is very much more noticeable than the more-or-less complete silence of a hybrid engine. If, as you're walking along, you were fussing with your shopping bags, or tugging on your dog's leash, or looking over your shoulder to see if the bus is coming, it would be very easy to get run over by a hybrid car without ever realizing it was coming.

      Hybrid cars also round streetcorners in front of you when you're preparing to cross the street. Some of the cross-streets on the street I live on are one-way, single-lane streets, on hills, with a building right on the corner. It's very easy to be surprised by a car making a lefthand turn as you're walking up the road -- even more so if the car doesn't make any noise.

      The problem isn't a crisis, but it really is about more than just accommodating "stupid people," or handicapped people who can't hear at normal levels. Regular people can very easily miss a hybrid car coming.

      Also, I think some of the people who scoff at this idea live in parts of America where you're essentially wedded to your car. There are many cities, however -- San Francisco, Boston, Portland, New York, Seattle -- where a lot of people, or even a majority, don't rely on a car for most of their travel. That means they spend at least part of their day on foot or on a bike on public streets. In New York and San Francisco, lots of people don't even own cars. So maybe you're not likely to get run down by a hybrid car every day, but if you're on the street every day, all year long... it could happen.

      Interesting. All the cars in my country are required to have a working horn. Does it make a difference just because the horn or bell is there? Or, maybe they have to - you know - actually ring it or press the horn? Saying bikes have bells is really like saying cars have horns. Apparently that isn't enough to fix this problem. Instead, they want the car to emit internal combustion engine sounds. Perhaps we can even get it to emit a realistic smell?

      You are making the assumption that pedestrian collisions are caused by the inattention of pedestrians. Assholes in hybrids will continue to roll through right-turns-on-red, ignore (or race) pedestrians already crossing, dart around between lanes for a single-car "advantage", zip through small neighborhood streets at 50mph, etc. In all of those situations, there is a defensive advantage because of sound. If that advantage goes away, the assholes just get more dangerous.

      Hmm.. Come to think of it, the police can solve most this by enforcing existing traffic laws. Once they start doing that, then I'll be in favor of reducing the noise pollution that cars make. In the meantime, they appear to split their time between catching speeders and only the grossest of safety violators, and I'll take the noise pollution over death.

      I take it you aren't blind and don't know anybody that's blind. The reason for this mandate is because pedestrians need all the help they can get to locate potential hazards. Seeing and hearing a car is vastly superior to just hearing it or just seeing it.

      And yes, I do look both ways, but that doesn't mean that I have eyes on the back of my head, so if I'm nearly half way into the lane as I cross the street, I can't necessarily see the car behind me that thinks it's OK to take a sudden right turn.

The injuries occurred when cars are parking, turning, and making other low-speed passes through pedestrian areas. In all likelihood, it is just as much the driver not paying attention as it is the pedestrian.

      To play Devil's Advocate, there is a rational reason for doing so.

      There is an elevated risk of rollover with an SUV, which I can mitigate as a driver by changing my driving style, and driving more defensively. A SUV helps me drive defensively by increasing visibility around me. Those are factors that I, as a driver, can control. However, I can't control what other drivers will do or the type of vehicle that will hit mine in an accident. Therefore, to mitigate that risk, I'll drive a larger vehicle that will provide more protection in an accident. Two problems are solved here.

      To go the opposite, way, driving a smaller car to manage the rollover risk decreases my ability to drive defensively (lower visibility) and decreases my chances of survival in a collision. One problem is solved, and another made potentially worse.

      I think you give the "bigger-is-safer" brainwashed drivers out there too much credit. I drive a sedan and a SUV and I can tell that the visibility thing is mostly a myth: you can't see past a minivan on either. This might have been true at some point,when big cars were few and far between but in this day and age SUVs give very little actual increased visibility. What people think is increased visibility really only means being able to stare down the normal size sedan right next to you.

      As well, there are common traffic situations where visibility doesn't really help yet size hurts. Say a car suddenly cuts into your lane. You either swerve and rollover, or step on the breaks, and guess what, because of your increased mass you cannot stop in time and run into the car in front of you. This is yet another way in which driving a larger car increases the chances of injury.

      The safest car is neither the biggest nor the smallest. It's one in which the engineers right-sized the brakes to the mass of the car, given it a responsive car suspension (hint: most large SUV were built on pickup-truck platforms), has good factory installed tires (ford explorer any one?), put a proper cage around the passenger compartment and don't burst into flames upon impact.
