This is the worst possible time to start an infrastructure project. The intermediate states matter, and construction sites are evil. San Fransisco's Vision Zero is why I haven't been able to cycle to work in two years. In the name of bicycle safety, the city tore out my bike lane and replaced it with a ditch. I don't really need it; I'm a confident vehicular cyclist and I'll take a traffic lane. But the lane I need to be in, which used to be a straight line, is now gated behind an extremely dangerous zipper merge around a half-finished bus boarding island. I have never been more afraid on the road than when navigating a situation allegedly intended to make me safer. The sidewalks in my neighborhood are being widened, and pedestrian bulb-outs are being added to make crossings shorter. Which means that for the forseeable future, the sidewalks are narrow passages between construction fences, and it's impossible to social-distance with oncoming traffic. The sidewalks around intersections are completely fenced off; to cross the street, you must get within inches of the cars. All of these things will be great to have, when they are completed in 2030. But until then walking and cycling are much, much worse than they would have been if things were left alone.
