Sans Casque?

In the sweep of history, four years isn't even the blink of an eye. But, even at my age--when you start to think of people within fifteen years or so of your own age as your peers--four years, especially if they're anything like the ones that have just passed, can seem like a geological age.

I'll spare you the cliche that "we are living in a different world" from that of 2019. (OK, since I've mentioned it, I didn't spare you from it, did I?) I have seen changes in my Astoria, New York neighborhood and in the city as a whole.  The passage of time, however, seems all the more sweeping when you return to a place you haven't seen in a while, especially if that place doesn't change as much or as quickly as your own environs.

While Paris is a modern city in terms of technology and infrastructure, its overall appearance doesn't change nearly as dramatically as that of New York in any given period of time.  You can count on returning to a building you saw in the City of Light four, fourteen or forty years ago.  Even some of the stores, restaurants and cafes you remember will be there if you return.  So, perhaps, that quality makes any change  all the more striking.

In my case, I couldn't help but to notice how many more people were on bikes than I saw during previous visits.  I'd heard and read that many people took to riding--for transportation, recreation and fitness--during the pandemic.  Apparently, they stayed in the saddle.  Of course that makes me happy.  I also noticed, on the other hand, e-bikes and scooters, which were nowhere to be seen the year before the pandemic.  I saw the proliferation of those vehicles in New York as the first weeks and months of the pandemic turned into years, but in Paris, it seemed as if they were all superimposed on the image I had of the city from the last time I saw it. 

One thing hasn't changed, though:  Almost no scooter-rider or cyclist, whether of the completely human-powered or electric variety, was wearing a helmet.  I admit that I didn't wear one, either:  It's not the easiest thing to pack, especially if you're traveling only with a carry-on bag.  But somehow I didn't feel as vulnerable or exposed as I do when I leave my apartment avec velo, sans casque.

I got to thinking about that when I came across this article. It points out, correctly, that the obsession with helmet-wearing is mainly an American one.  As the article's author, Marion Renault, points out, few cyclists in the Netherlands don the plastic and foam shells.  One reason, according to Renault, is that the Dutch feel safer while riding:  Their infrastructure lends itself to safe cycling to a much greater degree than what we have in the 'States.  Also, Dutch drivers' awareness and attitudes towards cyclists are very different from those of their American counterparts.

Something similar could be said, I think, for Paris and France, if to a lesser degree. Certainly, I felt safer, whether I was riding on a protected lane or in traffic.  About the latter:  Even though Paris streets are narrower than those in New York, I felt as if I had more room to maneuver.  Most likely, that had something to do with the fact that vehicles are smaller and lower to the street:  You don't often see anything like America's best-selling vehicle class: the Ford F-Series, which weighs 7500 pounds and has a hood that stands four and a half feet tall--about the height of an adult's chin.




That brings me to another point Renault makes:  most helmet testing does not, and cannot, measure the impact of a collision between such a vehicle and a cyclist.  For one thing, it's all but impossible to replicate such conditions in a laboratory.  There are more variables in such collisions than there are in, say, a clash between (American) football players.  

One of those variables, as I implied earlier, is the driver him or her self.  When I was doored two years ago, a nurse in the emergency room declared, "Good thing you were wearing your helmet."  While that was probably true, I would have been safer had the driver glanced out her window and seen me on the other side before she opened her door. I think a lot of French and Dutch riders would agree.  They also know that having good bike lanes, room to maneuver and traffic regulations that makes sense do at least as much as any piece of protective gear to promote their safety:  Their cyclists' rates of injury and death are much lower than those of their American counterparts.

So, if and when I return to Paris or Amsterdam, or anyplace else in France or the Netherlands, will I see as few cyclists wearing helmets as I saw during the trip I just took?

How Strong Does A Helmet Need To Be?

Current bike helmet testing procedures are fairly rudimentary.

That statement comes from two Swedish companies whose names are associated with safety.  One is well-recognized by Americans:  Volvo. I can recall when the company's ads included the claim that their cars were "the safest" on the road.  The other is POC, which makes helmets for cycling as well as other sports.


They have a point:  Most helmet tests "involve being dropped from different heights on either a flat or an angled surface" and might mimic low-speed falls onto curbs.  They do not, as Volvo and POC state, "take into account vehicle-to-bike accidents."


Previously, the two companies collaborated, along with Ericsson,  on another project aimed at making cyclists safer in the presence of cars.  In January 2015, they exhibited a prototype of a car-and-helmet system created to warn Volvo drivers and cyclists of their proximity to each other which, the creators believed, would prevent crashes.  That system, however, was not developed commercially.  As noble as the intentions of its creators may have been, such a system is fairly useless--unless, of course, the car and helmet have compatible systems.  That would be the case for the small percentage of drivers and cyclists (outside Sweden and a few other countries, anyway) who drive Volvos and wear POC helmets.




Now, a helmet that can withstand a collision with an automobile might be more practical. Still, I think it's fair to ask:  How much more practical is it?  Are there any studies that show how many collisions involve the cyclist's head slamming against the hood (or some other part) of a moving car or other motor vehicle?  


If a cyclist is run down from behind by a motorist who blew through a red light (as happened to Frank Scofield), how likely is it that the cyclist's head will make contact with the vehicle?   I can't help but to think that in such a collision, or the one that took the lives of five Michigan cyclists three years ago, helmets, no matter how strong, might not have made the difference between death and life, or prevented permanent injuries.

Don't get me wrong: I am in favor of making helmets safer.  But I also think they should be designed to protect cyclists in the conditions they have the greatest chance of encountering.  If someone can show me that a helmet made to withstand impacts with motor vehicles  can prevent , or could have prevented, fatalities in a significant number of crashes, then I'm all for what Volvo and POC are trying to do. Otherwise, I have to wonder just how useful it actually is.
