The Shallow Cogitations blogger did some investigative work and found the Spokane Police are issuing fewer no-helmet citations this year than in the past. When I weigh the pros and cons of riding without a helmet, this helps allay the fear of getting a ticket.
A few things keep me riding with the plastic and styrofoam lid in the heat:
1. I can ride some quiet, low traffic streets to work, but I know I'm still likely to make a rider error and crash all by myself. Slipped on some ice last winter on the Centennial Trail and hit my noggin on the pavement. Was glad I had my helmet on.
2. Although the police are handing out less citations, I regularly see the Bike Patrol downtown. Chances are good for a ticket. Hardly saw them at all last year, but saw them frequently 2 years ago. I think they changed their route to cover a wider area last year, now it looks like they're back to more frequent rides through the downtown core. (Couple years ago I was stopped at a light and they were talking to a young guy without a helmet nearby. They pointed over at me as an example of how to ride. I felt totally uncool.)
3. Whenever I mention riding without a helmet, my wife gives me the look.
