Considering that about half of workers in NYC do not have a car & no one should ride a train now, a modest proposal:

62% of the residents of Copenhagen commute to work by bike.

It can be done. Gotta close roads to cars and change mindsets, but the secondary benefits are huge. https://twitter.com/DaveCoIon/status/1266421742785961984

NYC finally legalized e-bikes. If people have completely car-free corridors to bike to work, they will -- you can see this in bike-friendly cities all over the world. If Copenhagen -- average winter temperature, just above freezing -- can do it, pretty sure NYC could too.

If suddenly millions of people are willing to never go out, work from home, *and* home-school their kids, hard to see transitioning to bike-focused urbanism being any bigger a lift.

Again, it works for Danes. *Nothing* stops their bike commutes: https://copenhagenvikingbiking.tumblr.com/
