Sorry, this is a Stan and Gordon, "Epic Feature Length" post. The fingers just took off - what can I say!:
Someone wrote: "Seriously, is it safe to jog with ear buds when/if you can't hear sounds that may warn you of impending danger? I see a lot of joggers doing this, and I really worry that they won't hear the noises they really should hear."
Yes, it seems perfectly safe, if driven by normal sound levels and "rules of the road". All of the "reports" about ear buds blocking out all of the ambient noise so that joggers (or bikers) can't hear overtaking cars has not been, in my experience, substantiated, and usually used as an argument by lawmakers who have no clue what's really happening out there - Hell...They don't even run or bike!
Look.....I've been wearing ear buds when riding my bike for years. They are NOT "noise canceling" models, meaning that I can still here 'real world' sounds happening around me, probably a whole lot better than sitting in a modern, insulated car with the radio cranked.
Yes, I can certainly hear BOTH overtaking cars as well as approaching cars. I can also hear birds chirping in the trees, people talking in their yards (but I can't make out what they're saying), the clicking of my chain when I'm not centered on a gear and all that sort of stuff, WAY better than sitting in a car. I almost never get surprised by an overtaking vehicle. We know what's happening around us.
So, let me ask this: Do you personally know of a runner or jogger who has been struck from behind by an approaching car? Runners in America are supposed to run against traffic. They should see approaching traffic and should be able to avoid it. They are at least 9 feet from overtaking cars from behind, on the other side of the street. And it's hard to get hit that way, unless they're (either the car operator or runner) doing something they shouldn't be.
Cyclists in America legally ride with traffic and cannot see overtaking vehicles unless they have rear view mirrors (and most people I ride with have such). These can be either handlebar mounted or helmet mounted, either version providing a good view of what's behind them.
I, personally, have been "dusted back" (pushed toward the shoulder) by a few cars who don't provide safe (or legal) passing distance. I consider anything under 3 feet an unsafe passing distance. The state considers 6 feet the legal minimum. I have had cars as close as 6 inches who don't even slow down.
I have been regularly riding at least 20 miles per day since 1980, racking up over 60,000 miles in that time. I have been hit five times in all of those years. ALL of those hits were before 1985, before the advent of decent ear buds. All of those hits were the fault of motorists, not me. None of those hits could have been avoided by me (believe me, if I could have, I would have). All of those hits were from oncoming traffic entering my lane illegally from the left or from a parking space. None of them were from behind. Every single one of the people who hit me said that they "didn't see me". I wear fluorescent yellow or green tunics, ride a fluorescent green bike and yet, they didn't see me. I am convinced that, once my wheels start to turn, both me and my bike become invisible, and I ride as such. People don't see me, so I have to anticipate their dumb movements and ride defensively. That has kept me crash free (and alive) since 1985, my last big hit. All of my friends ride this way, too.
In my experience, I have never been convinced that the use of ear buds is a hazard to either the cyclist or the surrounding motorists, UNLESS the earbud user has the volume cranked over 90 decibels to become distracting - if that is the case, there is the potential for ambient sound masking, but 90 decibels is a pretty loud level. Still, some people may ride/run like that, and if they do, accidents are they're own fault. There are dumb runners/bikers, just like there are dumb drivers.
I don't go out looking to get hit. It took me a couple of years to get over the last hit so I don't go out looking for it. But I approached using ear buds and music as a method to overcome boredom AND as a training enhancement, with an eye towards my own safety (I can also take a hands-free, incoming call from my wife, if I've been out too long and she's worried).
I go out for 3-4 hours at a whack. Using tracks from "Footloose" to get me over hills, helps. Knowing that I can hear overtaking vehicles is a safety feature which I don't jeopardize. Many other runners and bikers are the same as me. Yes, there will still be the odd-ball who runs/bikes with NWA or AC/DC cranked to overcome all outside noise. I believe that Darwins "Survival of the smartest" will take car of them.
Show me facts that tell me that using earbuds is a safety issue for my riding or running experience and I'll consider changing. So far, that has not happened.
Sorry for this excessively long post. My fingers made me do it.........
