I laugh at how in this article that foot traffic is seen as a bad thing. HN has seen hundreds of threads opining on how we should get rid of car lanes and open up space for pedestrian traffic. But this article talks of pedestrians as a scourge to be eliminated. Cops in cop cars are out there keeping the sidewalks clear of people. How many pedestrians or mass transit riders, fearing police encounters, will op to travel instead by private car?
