So do tickets, and I disagree with this being about education...most of them know what the rules are, they just don't care. I've had numerous "encounters" where I've tried educating one of these human door knobs and all you hear back is an angry tirade, threats, etc. I've worked for neighborhood bike works, a local cycling community group, and have seen these same people who want free bikes from us ride away on the sidewalk after lessons about proper cycling. I'm firmly in favor of the stick with this group over the carrot. Ticket them on the spot, confiscate the bike and let them pick it up after they pay the ticket.

You have a large group of people riding bikes in town because they broke laws driving cars and lost their privilege to drive them. So the same people who didn't respect the rules while driving are now using less regulated bikes. Hilarity ensues.
