Zipcar, which offers hourly rentals, has cars at several East Bay locations: in Emeryville, Berkeley, Concord-Walnut Creek and Oakland. City CarShare has vehicles in Alameda, Albany, Berkeley, El Cerrito, Fremont and Oakland.
Hertz has just two short-term rental locations in the Bay Area, one in San Francisco, the other at St. Mary's College.
Competition also is growing with peer-to-peer rental services, such as Wheelz.
If you use hourly car rental services, what experiences have you had? Do you prefer one service better than the others?
