Maybe Helsinki isn’t special: just fewer cars. And they apparently only 21% of daily trips used a private car.

Helsinki has about 3x fewer vehicles per capita than the average U.S. city. So it’s not surprising it’s safer since fewer cars mean fewer chances of getting hit by one. Plus their cars are much smaller.

In fact, there are probably plenty of U.S. towns and cities with similar number of cars that have zero traffic deaths (quick search says that Jersey City, New Jersey has zero traffic deaths in 2022).

So maybe it’s not about urban planning genius or Scandinavian magic. Maybe it’s just: fewer things that can kill you on the road.

I wonder how the numbers will change when majority of cars are autonomous.

The question to ask is, why are there less cars?

Public transport. As an example, just the tram network had 57 million trips in 2019. The metro, 90+ million trips annually. The commuter rail network? 70+ million. (Source: wikipedia)

So yes. Urban planning has a hand or two in it.

I completely agree. Though implementing it is far easier said than done.

Here in San Francisco (and much of California), things are incredibly complicated.

Take this example: in SF, there’s a policy that prevents kids from attending elementary school in their own neighborhoods. Instead, they’re assigned to schools on the opposite side of town. In places that are practically inaccessible without a car. And there are no school buses.

Changing that policy has proven nearly impossible. But if kids could actually attend local schools, biking or walking would be realistic options. That one shift alone could make a huge difference in reducing car dependence.

What kind of policy is that based on? Seems very counter intuitive, aren't are supposed to meet your classmates after school?

Essentially, this was the cheapest solution for our “limousine liberals” to address the problem of racial and economic segregation in San Francisco’s public schools. The idea was simple: since schools in areas like Hunter’s Point struggle, while those in neighborhoods like the Sunset perform well, the district decided to send students from Hunter’s Point to Sunset schools, and vice versa in order to “balance” outcomes.

But in practice, it backfired. Most families in the Sunset opted out: either by enrolling their children in private schools or moving out of city. The policy didn’t create meaningful integration; it just hollowed out neighborhood public schools and made traffic worse.

A striking example: St. Ignatius Catholic school located on Sunset Boulevard is now undergoing a $200 million campus expansion, while SFUSD is closing public schools due to declining enrollment.

It insane to me that anyone, let alone enough people to actually make it happen, would think that was a good policy. It's bussing, but without the busses.

There's a striking lack of accountability in politics. You don't really need evidence that a policy is going to accomplish it's stated goals, you just need the monkey brain narrative to resonate with voters (and the other elements of the political apparatus)

In the Nordics almost everything that gets passed as law has been thorough studies of impact and consequence first. Takes a long time but means the law has a chance of actually having the intended effect.

Ha, if only!

It's true systematic research on public interventions has historically been valued highly. The Campbell collaboration, Cochrane's sister project dedicated to public policy interventions, is based in Oslo.

But when some politicians wanted to praise and fund "centers of scientific excellence", it overwhelmingly went to the sort of high prestige research you'd expect, like neuroscience and AI. Politicians don't like being told what to do. Especially when the policies with scientific support from controlled studies are unpopular, as they often are (arguably, the study of public interventions against high alcohol consumption was how the Nordic's love of controlled studies in public policy came from).

Even uncontroversial things are decaying. Professor Dan Olweus, through controlled interventions, developed an intervention against bullying in schools in the late eighties. He pushed hard to get them implemented, and pushed back hard against "vibe coded" antisocial behavior prevention programs that didn't have experimental evidence. Bullying went down. But he died in 2020, and guess what, bullying is up again. Keeping government social interventions on the evidence-based path is constant, thankless work.
