Sweden went insane with road security in the nineties (nollvisionen?) so maybe that's why.

Sweden is as expected. 200-something fatalities for 10 million people. Norway stands out😃

It got me thinking about definitions, though. For Sweden every death during transportation is counted (including busses, heavy trucks and single accidents with a bike), while the definition my 2 minute googling found for Canada said deaths resulting from accidents involving automobiles.

Need to factor in terrain and weather conditions too.

Maybe scarier roads make you drive slower?

driving requirements for license are vastly different among european countries, but also state of the cars, more wealthy nations replace older cars more quickly, so countries like Bulgaria and Romania often sit on their cars for sometimes generations. Add to that the constant honking and cutting off people, temperament of the populus
