It's hard to judge a bike lane from a photo that only shows a few metres of it. The main problems with bikelanes are:

1. they tend to end abruptly when the lane it too narrow to fit it.

2. they tend to end at intersections, or worse, direct cycle traffic into dangerous situations eg. to the left side of a left turn only lane (right for you yanks)

3. incomplete coverage, and poor connections to other facilities eg. bike paths, train or bus stations etc.

4. debris doesn't get swept up often enough, if at all.

... to name a few.

I use a bike lane on my regular commute. I could take photos of it that would make you think it's as nice as the photos above, but I could also take photos [i]of the same bike lane[\i] that highlight all of the above problems.

My view is that I treat bike lanes exactly the same as a wide shoulder. I adjust my riding according to total road width, not whether there's a bike painted on it or not. I certainly don't divert my route from the shortest possible one just to ride on 'em.
