During this past year I've noticed an increasing number of drivers stopping short of the crosswalk lines by an ever increasing amount. Not too long ago most drivers stopped 3 to 5 feet short of that line. Today at least a third of them are stopping 15 to 20 feet away from those markings.
Why are they doing this? I've no idea. Why do I care? They're stopping short of the underground sensors that trigger the traffic lights.
