If you want to really affect change locally Steve-O, you have the opportunity. WSW sponsors several local riders. I encourage you to put your efforts toward making them the absolute best role models possible.
If they prove to fall short, simply take away the sponsorship.

Once others witness WSW sponsored riders practicing what you preach, it will surely have a positive impact.

It's fairly obvious that this approach could work nationwide to affect rider behavior. What's not obvious is anyone actually doing it.
