The European car numbers are so high that I'd guess the unit is the whole metropolitan area. Otherwise it sounds pretty bizarre that most cities would have car usage close to 75%

20% of people employed in NYC don’t live there. So that explains ~940,000 people who are probably driving.

13,000 vehicles in NYC are taxis. 77,000 active ride share drivers. These are used by the 176,000 daily tourists.

That brings the total number of cars in NYC largely serving people who don’t actually live there to 1.1m most days.

There are 2.1 million registered cars in NYC. That means 1:3 cars currently in the city represent people who don’t live there. That is roughly 1/3 of all cars in NYC. Likely closer to 50% or more of the actual traffic since the average NYC resident does not drive their car every day.

Yeah its the walking that got me. People walk a lot.

You might like Mackinac Island...

In the US, walkability is a luxury. Being able to afford to live in a walkable area is expensive.

It's a shame that the source didn't publish raw data

How about that sub-saharan city where 90% walk everywhere, also an outlier.

Venice?

My guess would be either London, Paris or Berlin

Edit: I think I misunderstood which data point you were referring to

Only 4% in Utrecht using public transit? Seems farfetched. Probably that is referring rather to those who only ever use public transit. Most use both bicycle and public transit.

This is a standard type of graph:

I was there in the trenches of the soil wars. They were made of loam.

Neat how all that data just fit nicely into a triangle too.

And they're barely trying. Latin American countries invest most of their transportation budgets into car infrastructure, even though the minority of citizens uses it. Why? Because Latin America.
Imagine what they could do if there was any political will.

Maybe with the new upcoming REM lines, car usage will decrease.

Drop into street view at a random intersection in Montreal and chances are you'll be able to see more cars than people. This is sadly still true for most cities in the western world, outside of their central business districts. We don't like to spent time in places where there are lots of cars so we bias ourselves, but most places still do have lots of cars.
