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.

It's worse than that. It's not even that "it's not expensive", it actually saves you money to take out lanes of traffic and making it into bike lanes, or running more and better public transport.

(1) More people biking and fewer people sitting in cars, not to mention lower pollution, mean you save money in healthcare for each dollar invested into bike infrastructure.

(2) In purely cold terms, killing e.g. a 30 year old represents a loss of productivity to the state in the order of millions.
