As one who used to bike (19 years) and actually obeyed the traffic laws and thus stayed out of trouble, I always got a kick out of the idea by bicyclists that that little helmet was going to save them when they got smacked by a vehicle because of doing dumb or criminal things like ignoring the rules of the road or riding stoned. The attitude amongst just about every bicyclist I’ve met from college on has been: I’m riding the wrong way, but I gots a helmet. We’re riding stoned and wobbling across the lanes, but we’ve got helmets. Run the stop sign/traffic light, but I gots a helmet, dooood. A completely clear bike lane to ride in? Naaah, I’m riding in the highway; it’s more fun to make cars try not to hit me. I’ll not pay any attention to where I’m at and turn in front of traffic. And so on..In the Pacific Northwest it’s been a matter of motorists desperately trying to not run over idiots doing illegal stunts for almost as long as I can remember. ODOT has some interesting crash stats on the matter. It’s extremely rare that it’s the motorist’s fault..And it’s almost completely avoidable. By obeying the traffic laws, exercising courtesy, and keeping a sharp (and sober eye out— it’s amazing how many riders are inebriated or otherwise impaired. Personally, I think it one step up from suicide) eye out, only twice did I run into problems with vehicles. It makes ALL the difference in the world for a bicyclist to remember that there are others on the road and to thus act accordingly.
