In the mid 1990s, the Bicycle Federation of America (now The National Center for Bicycling & Walking, but then consisting of but two industry lobbyists, one of whom is now the LAB/BFC head) was a sub-consultant on a bicycle transportation plan for a major US sunbelt city. They recommended bike lanes as the cure-all, whether appropriate or not. They got 'em, too (but not enough of them from their perspective, and so they distanced themselves from the final product).
Here's what those bike lanes look like today (the ones that haven't been removed). While I am sure there are better examples in this city, these aren't the worse, and they just happened to be the very first I came upon.
The trouble with pixie dust, even well-meaning pixie dust, is that it has a very poor impact on reality. Approaches like this should help you understand the second-class status that bicycle facilities advocates urge on cyclists, where the unwarranted fear-based idea of bike lanes results in cyclists literally (litter-ally?) being swept into the roadway gutter. The offensive term "gutter-bunnies" has a basis in reality. These are gutters.
Remember, under Texas law, these bike lanes are mandatory for cyclists. Sure, a cyclist can swerve out to avoid an obstacle... let's just hope there isn't a car or a bus passing.
