The evolution of the cab has come. For those who enjoy a night of drinking, two companies now offer rides home in your own car instead of one of the yellow checkered variety.

Leaders of BeMyDD, or Be My Designated Driver, and RAD, a.k.a. Rent-A-Driver, both say they offer peace of mind and convenience, since you don't have to retrieve your car the next morning.

"Really, the people using it are people who have something to lose," said Arthur Simanovsky, who launched BeMyDD with his friend Alexa Milkovich last March in Cleveland.

The company now operates in almost 20 cities in Kentucky, Florida, Illinois, Indiana, Maryland, Ohio, Texas, Virginia and Washington D.C. In Kentucky, the company serves customers in the Lexington, Louisville and Northern Kentucky areas and has been operating for several months.
