Serge, I see you actively working on convincing cyclists to your line of thinking, but..
What are you really doing about it?
Have you made any changes in your city plans for future bike stuffs? It seems to me that that would be more effective to your goals. Even when you discuss here, I don't see you talking about methods to make changes (however, i must admit to not reading these threads in entirely, they get a little repetitive after awhile). It really does not matter how many you "convince to thinking this way is better," if no one is working for changes. That just creates a bunch of bitter cyclists.
perhaps you should run for some public office that will get you in on the planning committee for your city construction zone. Or train some of your typing skills towards letter writing.
