Based on my experience living here in Helsinki for 30 years, people drive cars _more_ in the winter rather than less. That’s because the alternative is usually some combination of walking and public transit, and walking is uncomfortable in the winter and public transit is a bit less dependable, too.
But altogether people mostly still use public transit, there’s not a whole lot of driving per capita and the traffic is relatively slow and non-chaotic. I think that’s the core reason for the road safety.
Also, the requirements for getting a driver’s license here are stricter than it sounds like in other countries, with a high emphasis on safety; that probably contributes to the non-chaotic traffic
