Confusing Bike Lanes

Once again, DOT has done half a job. This time, its the bicyclists who are paying the fines, at least until DOT finishes marking out the bike lanes and making it clear that (in this case) bicycles are allowed on the sidewalk.
Is it really too much to ask that DOT think about what they’re doing before they break out the paint striper? Maybe the machine is just so much fun that they can’t stop the guys from going out and painting lines before the higher ups have thought the whole plan through.
