Zip-cars gaining popularity

HOUSTON, Texas. -- Living without a vehicle or think you could?

Rice University in Texas is testing that possibility with something called the "Zip-car."

As many students get around town the cars they're driving aren't actually theirs. To get a Zip-car students buy a year-long subscription for under $50 and then pay about $10 per hour when they use it.

"You can book it for however long you want on line, so you can say I need it from 12 to 3 and they tell you which car is available," said Molly McDonnell, Zip-car Driver.

If you think this sounds a lot like rental car, it is. The big difference is the annual subscription fee.
