I think they're to try and remind bicyclists that roads are designed for cars and they should probably stay away. Bicyclists don't get the hint.
I get the hint. There are no shortage of mental or emotional midgets who cannot seem to safely share the roads with cyclists. Is it the physical, psychological or intellectual part you find so difficult?
This thread started to point out the self-righteous, condescending attitude of most bike riders. I'm glad you're here to help moderate that opinion.
And based on the pictures you've posted of where you ride, no, you haven't gotten the hint. But at least when you get squished, you can pass on knowing you were killed by a mental midget.
