This is what you should think of when you are thinking about the huge number of pedestrian deaths per capita in the US. Why didn’t we leave the quiet arterials alone like Europe did?
“The difference (between US and Europe) is not how we design the streets, but rather what we allow to occur along the streets.”
Eric Dumbaugh
His 2026 peer-reviewed paper, Land Use and Road Safety, develops this argument with statistical analysis and field investigations.

The United States cannot replicate Dutch bicycle infrastructure while ignoring its own disperse separated land use due to its zoning, that make so many American trips longer, and much more automobile-dependent across all of its metros.

Allowing more housing to be easily built is probably the most progressive thing a government can do for its residents since housing is by far most people’s highest monthly cost.
A parking-protected bike lane may be inexpensive to install between intersections, but the intersection itself, where bump outs exist, will require substantial capital reconstruction as trees, drainage fixes, lighting changes, and space reallocation.

Originally a residential street, then zoned into a deadly commercial 6 lane arterial

“Land-use zoning, beyond its original purpose of separating housing from noxious uses, creates car dependence.”

"Leaving people with no other option other than car ownership is a huge burden for working class and middle class New Yorkers...Leaving some parts of the city with no option but to own a car is a policy failure."
10/10 no notes
What the commissioner said and what the Post wrote are two different things.
This is about affordability. New Yorkers deserve a range of affordable and efficient transportation options. They deserve fast buses, safe bike infrastructure, quality pedestrian space, and parking policy that actually works.
As he said, leaving people with no other option other than car ownership is a huge burden for working class and middle class New Yorkers. Between car payments, gas, insurance, registration, parking, maintenance, etc. it is way more of a financial burden than a monthly OMNY card that caps at $151.
Leaving some parts of the city with no option but to own a car is a policy failure. If people want/need to own one, that's totally fine. But, people deserve choices.

Yes, public transit is an 18th century idea. If it's lasted this long, maybe there's a reason.
Remember:
1. Many old ideas are good ideas.
2. Most innovations fail, or at least disappoint.
Don't throw away useful tools in return for airy promises.
