Amen!

Our campus bike path system looks great on the surface... it's only when you actually try to use it that you realize how nutty it is... if 90% of the time a path is okay, and you only endanger your life 10% of the time (sudden merges with the wrong side of a road, places you have to swerve around hazards, places where you're suddenly supposed to cross to the other side of a four-lane road - not to mention the "usual" conflicts of crossroads and driveways, trucks parking in the lane, that bus stop that's in the middle of it...) , that's still NUTS but it looks great from your car window and it means you can holler at the cyclists to get on their sidewalks/paths where they belong.

It's a complicated topic, though, and to top it all off so much depends on the specific traffic dynamics and culture of a given community.
