7. San Diego
Number of car-sharing locations:
North Park, University City, Pacific Beach
Trolleys, buses, light rain, commuter rail, thriving bike culture ... why does San Diego need car sharing again? Well, occasionally you're going to have to transport something that won't fit in any of those and, in San Diego, sometimes life takes you up or down Interstate 5. Suffering but stalwart San Diego Chargers fans know this all too well, but so do folks who are just looking for a ride to the beach or a way to get out of the city for a few days. When the weather cooperates, and it often does here, it can be a lovely day for a ride even for those who are usually car free.
