Of course, but you pay for it, with new Rohloff hubs starting at £700 compared to Shimano 11s or Sturmey Archer 8s from £150 and Sturmey 3s starting at £15.
I still suspect most people are shifting with a cable rather than a spanner! And there are occasional reports of Rohloffs slipping, mostly in cold weather, like

Not only did I not read all of all of the Rohloff site, I'm not sure whether I read the intended bit(s) of the intended page(s) because the post that sent me there was almost completely directionless and barely better than JFGI.
