True, but I believe that without addressing the underlying behaviour/beliefs, the problem will just resurface sooner or later. It may even make the problem worse. However the very act of debating and/or adding those incentives may produce a great deal of social change. That's why I wish Ontario would discuss a 3-foot passing law - I'm sceptical it would be effective or enforced, but the added attention would be good.
