One of my ongoing gripes is that there is absolutely NO widespread availability of education for road-going bike riders. And unfortunately, some never get educated about what's proper and improper; or worse yet, they get bad information.
(Somebody has probably told all those wrong-way doofuses that, like pedestrians, they're somehow safer if they're riding towards oncoming traffic. You'd think that their on-street experience would quickly make them realize how many additional hazards they expose themselves and other roadway users to. If you're not observant enough to recognize it... maybe you don't belong on public roadways.)
But... who should take the lead in an education effort?
Supposedly everybody who possesses a driver's license has taken both a written test and a driving test. (Which would suggest competence. However we've all observed that while some licensed drivers are extremely competent, others really have no business on the road, licensed or not. Humorist Dave Barry observes that "We all share one thing in common - we think we are better-than-average drivers.")
Since you don't need a bicycle operator's license, there is no equivalent written or practical test. Thus you lose a bit of incentive to learn safe cycling skills.
Also - and I believe this is significant - since the police rarely enforce bicycle laws unless an accident is involved, there is also not the incentive to ride legally and safely to avoid getting a traffic ticket. (The police are totally responsible for that situation; I sincerely wish they'd prioritize bike traffic at the same level as motor traffic. If tickets were regularly handed out to cyclists who break the law, I can almost guarantee more compliance would follow, and subsequently fewer bike-involved accidents.)
What would my suggestion be?
I would like to see the police teach a 2-hour OUTSIDE bike safety course, maybe starting in 4th or 5th grade, and every year up through high school. Geared to the level of the students. They could do it in the autumn while the weather is still beautiful, and resume in the spring. Outside - where safety practices could be demonstrated and perhaps even rehearsed - would be much more effective than a "theory lecture" in a gym or classroom.
Portland is doing something different - the Portland Water Bureau is sponsoring a "Bike/Truck Safety Event" on Saturday, June 6th. (Info HERE.) The event is intended to "spotlight safety concerns of bicycles and large trucks sharing the road." The Bicycle Transportation Alliance is helping; evidently they did one last September that was quite successful.
(Hmmm... who woulda thunk that the Water Bureau could teach bike safety? That seems unlikely, but also demonstrates some "out of the box" thinking. I like it!)
