I don't know, I ride in the street right next to a completely separated MUP path near my house all the time. The MUP is a mixture of joggers, dog walkers, strollers, rollerbladers and folks riding their bikes recreationally at <10mph. My average moving speed on that stretch is ~18mph, it's just far safer for me to ride in the street for all parties.
