We love us some ZipCar, but Scoot Networks is cheaper, cuter, and you won't lose your mind trying to find a parking spot in San Francisco. It's still in Beta mode, but rumor has it you'll be able to reserve an electric(!) scooter at various neighborhood locations using their mobile app (like ZipCar) and your phone serves as the key when it recognizes it. Looking tech-y and eco-friendly and just plain rad for just $5 an hour? Yes please.
