Bike lanes are the product of self-indulgence among the upper middle class, and environmental ideological activism by progressives. They make no earthly sense in our environment, and are mostly unused. They narrow roads, choking traffic, the cost of which is enormous, and so, ultimately, produce more pollution by creating traffic jams than their few users can possibly save by abandoning their cars.
Yawn, get off your duff and bike and you will see how well they are used.
