Hi, welcome to OSM! I've noticed you've changed the highway classifications of a number of roads all around Northern California. If you don't mind me asking, what's your rationale for these changes? In this particular example, I've driven much of CA 1 in this area, and it's not a big thoroughfare connecting major population centers, but rather a one lane road connecting to small, rural towns and recreational areas. So I think primary is a good fit for it.

In addition, which roads to classify as trunk in California were recently hashed out by the mapping community and documented at https://wiki.openstreetmap.org/wiki/California/2022_Highway_Classification_Guidelines, and these segments aren't on it. If you think they meet the definition of trunk, it'd be nice if you discussed it on the talk page there.

Best,
Will
