Which part of this says "Parking Space"? The posts, the green paint, the sharrow markings, the "No Stopping" signs or the sidewalk? Hey, United States Postal Service, YOU CAN'T PARK HERE!!!
And while I am at it, San Francisco Department of Public Works, just in case you didn't get the memo, YOU CAN NOT PARK IN BIKE LANES, ESPECIALLY WHEN THE ADJACENT TRAFFIC IS DRIVING MORE THAN 50MPH!
Just because you are "official" does not give you the right to be "officially" blind, selfish and discourteous. Enough said.
