I find it’s the people who don’t ride regularly that are the worst culprits. Most (but not all) avid cyclists wear helmets consistently.
These infrequent cyclists are people with the lowest bike handling skills, least road sense, poor cycling etiquette, and are at the highest risk of an accident/collision.
On Saturday when I was out for a ride in the city (wearing my helmet), the pathways around downtown were packed. I passed dozens of people who (IMHO) were on the verge of crashing, or causing an accident.
So, even if you feel you are a rockstar cyclist and would never crash on your own, you can’t always account for the actions of other people. Even if you aren’t seriously injured, crashing on a bike just sucks in general. To me, it doesn’t make sense to take that chance.
My rant gets taken to a whole new level when I see parents not wearing helmets when riding with kids (in almost every instance, the kids are wearing helmets).
What are these parents thinking? What message is this sending to the their kids?
Perhaps they believe that adult heads are immune to damage from concrete and asphalt.
In reality, it comes down to the old “do as I say, not as I do” mentality.
This situation likely exists because people don’t take the time to think about the impact of their daily actions. Taken further, this situation speaks to the larger picture about your personal “brand”, your “values”, and what you believe in (but that’s for a different post)
