That would seriously depend on 'what part' of California you are talking about. In the cities and down south where parking and traffic are huge factors, you bet. But the farther north you go the more trucks and large SUVs you will see on the road. California is far too big to be treated as a single entity when it comes to anything.
Arguments that the empty part of California is huge and therefore important baffle me. 99% of Californians live south of Yuba City. 90% of them live south of Lodi. Half of them live south of Ventura.
Yes the incredibly empty "Empty Quarter" of the state is large, and empty. As in nobody lives there. The best-selling vehicle in Modoc County may or may not be a truck, but the fact is of no interest.

Really, INME, just “in the cities” (with maybe also the coastal mountain areas between the coastal cities). The inland rural south is no different than the inland rural north in this respect, AFAICT.
