It can, because annual mileage is one of the main factors California insurers must weigh. If you drive less than you used to, report that so your quote reflects it.
Should Castle Hill drivers add theft protection to their policy?
Contra Costa County's rate of about 3.4 thefts per thousand people is slightly above the state's 3.2. Comprehensive coverage pays for theft, fire, flood and vandalism, so it is worth considering, especially for a newer car.
