...to make bike lanes safer.
By painting a stop bar and a stop sign stencil at each intersection (controlled or not), many of the egregious design faults of bike lanes could be minimized. Right hooks and left crosses would now have a designed-in counter measure to protect the not-so-Swift cyclists from the unexpected.
After all, bike-lane cyclists never run stop signs.
Hat tip to LAB Bicycle Friendly Community Flagstaff, Arizona (which has a law requiring bicycles to yield to oncoming "real" vehicles) for this great idea.
