I was very surprised.
I didn't even know.
It turns out that in Russia the share of roads with hard surfaces is more than 71% of all roads.
and in Canada only about 40%.
Data from two years ago. But I don't think the statistics have changed dramatically in two years. In the US, it's about the same as here: 70% hard coating, 30% no hard coating. Of course, we are inferior to Europe, where there are almost no primers. But the size of the countries there is infinitely small, and so is the length of the roads.
