It really depends. In my experience in the Northeast, when speed limits are 70-75 mph in more rural locations, I don't see most cars traveling at 85.

80ish dropping to 70 for tight curves and other "features" is pretty standard for everywhere in the Boston-RI-CT-NYC corridor for pre and post rush hour.
