The above was referencing stopping on a city street ("Powell between Bush and Sutter"). You're talking about stopping on a highway. These things are not particularly comparable.
In the California Vehicle Code section 360, a "highway" is defined for the purposes of the vehicle code as "a way or place of whatever nature, publicly maintained and open to the use of the public for purposes of vehicular travel. Highway includes street." [0]
