Few companies connected to the auto industry can resist the allure of starting their own car sharing service, it seems. After a brief tease, AAA's venture wing has launched Gig, an app-centric car sharing service, in Berkeley and Oakland. You pull out your phone to rent a car like you would with rivals services like Zipcar, at rates of $2.50 per mile, $15 per hour or $85 per day. However, there's a bit of a twist. You don't have to find a special point to drop your car off -- Gig has made deals with its host cities to let you drop your car off at any metered parking space or public parking lot. If you'd rather not take a detour just to end your trip at an approved location, you might not have to.
