I recently became licensed by the California Public Utilities Commission. This will allow me to drive my visitors around the Bay area in my car. (My SUV can comfortably seat 5 persons.)
In San Francisco, a car means driving down Lombard Street or up steep hills, ogling the beautiful mansions of Seacliff, or venturing off the beaten path in Chinatown. (all these areas are inaccessible to buses)
In Silicon Valley, a car allows for greater flexibility to drive past historic garages (there are several), through a Palo Alto neighborhood or up a winding hill to a viewpoint.
Let me know if you would like to plan a custom itinerary using this new service.
