Around here, many roads that will be plowed have cats eye reflectors, but they're installed in divots in the pavement rather than surface mounted. Makes the bumps from driving on the lines a bit more pronounced, but the sight lines on the reflectors are somewhat impeeded and they also collect road debris.
I remember having a similar feeling when I drove in Iceland. I think their roads were super helpful, even at night/snow. I forget why/how exactly, and they salt/plow, too. Maybe theirs are sunken, to allow for plows?
