Data per registered vehicle is interesting. The number for North Korea is truly mind-blowing. Could be something funny about how registrations are handled there idk

Possibly. I think it's more that places which needed air conditioning in order to be habitable developed later and ended up with 90% of their development being suburban sprawl. Pre WWII development is safer.

I used 1940 because urbanization in 1940 is actually a better predictor than urbanization today.

Vehicles are a factor but the development pattern in a state is also a significant predictor of road safety. The places that urbanized after 1940 (urban per the census includes suburbs) are less safe than states with more pre war development.

Jug handles help but on the other hand you have the horrifying zero radius turns from parking lots that go right up to the edge of the road out into multiple lanes of 50+ mph speed limit traffic on what is otherwise designed like an interstate highway with Jersey barriers down the middle

I see why people always have this thought, but to me that's like dividing lung cancer deaths by how many people smoke. Even so:

For sure. A lot of people are within walking distance of their local grocery store in theory, but there's a fence in the way that makes them go all the way around, or they have to go out of their way to cross a busy road, or there are no sidewalks/crosswalks, or it's unsafe even with those.

The funny thing about New Jersey is they have some of the safest drivers in North America, per mile. I think they're just assholes because the roads in that particular state (and Massachusetts) are designed in a way that you HAVE to be aggressive.

Insane but true fact: making US roads as safe as Canadian, Australian, or European roads would save more lives than eliminating murder from the US.

The funny thing is the Paris area only has like twice as many people yet it has 20x as many train stations. And even the Paris area doesn't have a ton of people, there are six 100km circles around the world with 60+ million people (Dhaka, Delhi, Jakarta, Hong Kong, Shanghai, Cairo).

Back of the envelope analysis shows Chicago needs to double the amount of housing within 5 miles of downtown and add ~635,000 people to this area.

Compiling a dataset of how many people are within a 1 hr walk of city centers around the world vs how many are within a 1 hr drive of city centers in the US using Tomtom congestion data and "population around a point". Houston slightly beats Dhaka. Chicago slightly beats Karachi.
