That's about seeing things in photographs taken from space, not things seen with the naked eye. Like, we've all seen satellite reconnaissance photos, so we know those can see lots of important stuff.
Astronauts can reportedly see highways, airports, dams with a naked eye from orbit.
Do you have a link to those reports? Highways strike me as improbable. Visibility requires thickness in 2 directions, so if they could see highways I'd expect them to see tons of stuff, like wharehouses.
