Beep, Beep!


I’ve had my Toyota Prius for two years now….  I still like it, too. I had to learn to drive it, though.  No, it’s not stick shift or anything else difficult to learn.  The problem is it’s quiet.  Too quiet.  Moving at less than 15 mph, it’s on electric power and, well, electric power doesn’t make any noise….

In 2009, the National Highway Transportation and Safety Administration found that EVs and HEV’s (electric vehicles and hybrid electric vehicles like the Prius) were twice as likely to be involved in a pedestrian-related crash as traditional vehicles.  Of course, it was a small test but the handwriting is on the wall: by 2015, 1.5 million electric vehicles are predicted to be on the nation’s highways. http://www.foxbusiness.com/personal-finance/2011/09/07/what-should-electric-car-sound-like/

So, they want to do something to prevent pedestrian injuries. 

I know what they mean: moving through a parking lot—in stealth mode—can be dangerous.  I have to remember that, even though I can see the people walking in front of me, they cannot hear me.  Moving at approximately 5-10 miles an hour, my little Prius doesn’t make any sound…

So, what to do?  I guess I could roll down the windows and play my Queen CD:  I am sure that “We will, we will ROCK YOU!”  would garner their attention.  Or would it?   Considering how my car vibrates at a stoplight, thanks to the car or truck behind me playing “music” loudly, I wonder if anything I played would be loud enough to be heard.

And what if it was raining?  Or freezing cold?  How can I be expected to roll down my windows and get drenched just to protect a pedestrian?  No, that’s probably not the answer…

And then, there are the folks with their ear buds in their ears…..but I talked about that in another blog.  The consequences of tuning out the world around us can have very dangerous, fatal consequences.

So, with 100 different brands of electric vehicles, or hybrid electric vehicles, projected to be available in 2012, I think something has to be done.   Even if I am paying close attention to the pedestrians in front of me, nothing says that someone can’t dart out in front of me in a split second.  Too quickly for me to brake and avoid hitting them….

Now, the question is: what noise will these electric cars make?  Of course, we all know the sound that a truck makes when backing up.  And the sound of sirens.  Some of them “chirp” when the turn signals are on.  Or whirr…or whatever. There has been a suggestion that EVs could sound like an engine revving, but that seems a little aggressive to me.

What sort of computer-generated noise would “announce” to pedestrians that an EV is behind them?  What noise wouldn’t become so mundane that people chose to ignore it?  Perhaps that doesn’t matter.  Perhaps all that matters is that EVs tried to warn them….

Maybe with some sort of external, weather-proof  speaker….and a little imagination….
