For me, setup like this is not a replacement or even supplement the desk + high focus environment. My use case for these mobile vibecode setup is great though for small exploration/POC/learning/research type of work. Then I take the knowledge learned or any actual useful parts of code and incorporate into my work next time I sit back down at my desk.
NYC is a new set of challenges. As you already mentioned snow and ice is new. But also missing the high density of people and cars per square area. Behavior of drivers and pedestrians are different and much less polite. I can see it working in NYC but "just fine" is a bit of an over confidence... at least not for the first few years before they learn to deal with these issues that they don't face yet in LA and SF.
I think most protesters are optimistic that if they can keep on winning each political battle like this, something dramatic can happen in their favor in 2047.
Also even if nothing can be changed, one perspective is that it is better to vocally reject rather than accepting in silence.
