Good question.  The city of Eugene continues to eliminate or "reassign" traffic lanes to make room for bike lanes (ex: S. Willamette) along major transportation routes, saying they want "20-minute" neighborhoods.  But, most family wage jobs are located outside of the city limits, so people drive.  The net results is worse congestion with empty bike lanes.  

I've always said that the safest bike routes are on residential streets.  Who in their right mind wants to ride alone side of a parade of bumper-to-bumper traffic?
