Zipcar’s 9,000-plus fleet of vehicles has brought the car-share model of urban transport to 15 metropolitan areas in the US, Canada, and the UK. A $60 annual fee gets you in, and rates start at $7.75 an hour (gas included). Tell the app where and when you need a ride, and use the virtual key fob to unlock the car when you arrive.
