Testing on Saera (which still has an optional GraphHopper backend) the directions are still awful - the directions on the route I tested were basically "Head north", "Continue", "Continue", "Continue", "Continue", "Turn left on X street" - where the Continue's should have been interpreted as "Take the ramp onto the interstate", "Merge onto the interstate", "Take exit Y", and "Merge onto Z street".

Edit: Also might want to add Google (impossible terms) and Bing (impossible terms) to that list.
