Helsinki records zero traffic deaths for full year

This is one of the things I find difficult about travelling abroad, particularly with children. I'm used to incredibly high safety standards, and when I'm in traffic in many other places in the world it feels like going back a few decades.

Genuine question: we have a lot of research on how not to die in traffic (lower speeds around pedestrians, bicyclists stopped ahead of cars in intersections, children in backward facing seats, seatbelts in all seats in all types of vehicles, roundabouts in high-speed intersections, etc.)

Why are more parts of the world not taking action on it? These are not very expensive things compared to the value many people assign to a life lost, even in expected value terms.

Tangential: I'd love to vote for a political party whose only thing is to copy stuff that works in other neighbor countries. Everyone wants to reinvent the wheel or is too proud or something, idk.

You're basically describing Volt Europa. They're having some success with that approach in Germany and the Netherlands, primarily at the municipality level

The last election must have been around the recent middle-east events (framing it purposefully neutral), because I remember I had some conflicting thoughts about their stance. I can't (honestly) remember if I voted for them then or not - but I strongly considered it, that much I know.

Edit: Writing this out I think, I'm probably part of the problem. Voters should remember who they voted for and benchmark the results against their campaign pledge. Keeping politicians responsible with the little power we individuals have.
