In NYC, the protected bike lanes are typically one-way by design; but if you ride on one, be prepared for "bike salmon" (coinage by The Bike Snob, I believe) coming at you on e-bikes and even combustion-powered scooters -- and they're not all delivery guys either. I actually feel safer riding with the automobile/bus traffic. The bikeways in parks are pretty much the same, though at least those are two-way; but the runners/joggers have decided that they can use them too (even though clearly marked for use only by non-motorized bikes, scooters and roller-bladers, and there are separate lanes for pedestrians and joggers. Honking by car drivers (illegal in NYC except for emergencies) has become endemic (a good toot or three at practically every change of the light to say "get out of my way"), and of course the ban is never enforced by our Finest. As a rider on streets, I have noticed that many times cars passing me will come within inches, leaving more gap on the driver side than on mine.
