The soon-to-be-ex-mayor of Seattle is pushing hard for bike lanes everywhere, but it's probably the single issue that will cause him to be thrown out of office.
Seattle'c cyclists have an overwhelming culture of disregard for traffic laws, disdain for pedestrians, and no respect for other vehicular traffic. For example, on one of the major arterials I commute through, fewer than 1 in 5 cyclists stop for ANY red light over the busiest 2-3 miles. If traffic is busy, around 1 in 4 will just ride on the sidewalk thru groups of pedestrians (which is illegal) without signaling (which is illegal) without following traffic OR pedestrian signals (which is illegal). No one knows what the green bike lanes mean to vehicle traffic (there's no clear law), and the "sharows" (chevrons + bike icon painted on the road) are intended to encourage lane sharing... but there's no public guidance or traffic law specific to them, and they've been plunked down all over the place with little planning (e.g. on narrow high-speed roads for which NO slow vehicle is appropriate) -- which leads to confusion from motor vehicles and even more reckless behavior by cyclists. And to compound the whole mess, cycling is very seasonal here (it rains some in Seattle, and the city is only slightly less hilly than SanFran)... so most lanes are very lightly used (zero to maybe a couple dozen riders a day) outside of summer months. It's funny how the mayor's cycling lobby is really loud about how many miles of bike lanes implemented (i.e. motor vehicle capacity reduced, and idling/pollution increased), but dead silent on usage metrics (which isn't a little low, it's a lot low... like an order of magnitude low WRT justifying removal of MV capacity).
I have a decent bike, and I ride. My adult-size kids commute to school by bike+bus. I *like* cycling. But ironically Seattle's inane and badly-planned bike-lane implementation, combined with the reckless/arrogant road behavior encouraged by the likes of the nutbag Cascade Bicycle Club*** has created such confusion and hostility on the road that I don't feel safe riding anymore.
(***Just because I ride does not mean that these arrogant idiots represent me. If you live around Seattle, think about that next time you see my kid riding home from school, after you've been stuck behind a Cascade-sponsored rolling roadblock. And think about your vote for Mayor, as you sit idling on Greenwood Ave, recently cut down to one single lane, in a 3-block backup
