They remove the parking during rush hours. However, motorists still park. They drop off or pick-up. They leave late or arrive early, so they park. They need their all important "quad long shot grande in a venti cup half calf double cupped no sleeve salted caramel mocha latte with 2 pumps of vanilla substitute 2 pumps of white chocolate mocha for mocha and substitute 2 pumps of hazelnut for toffee nut half whole milk and half breve with no whipped cream extra hot extra foam extra caramel drizzle extra salt add a scoop of vanilla bean powder with light ice well stirred.... oh by the way, I have a free reward."
So really there is no need to remove parking in the curb lane, for whatever reason, because it would be ignored. Just like motorists ignore the painted cycling lanes.
