As someone who walks in Manhattan, I see where you're coming from, but my experience differs. Specifically, 99% of the time I'm walking in Manhattan, I'm not trying to get somewhere on the same street or avenue I started on, so I can turn and walk along whatever block to avoid the lights. Plus (at least in the 40s), there are plenty of subway entries/passages where you don't need to pay but can pass through to get underneath the street - and buildings you can pass through as well. Of course, figuring out this maze is half the "fun" of walking in Manhattan.
