Driver on Demand Service

About a month ago, I read an article about the benefits of drivers on demand. Then a few days ago I read a news about companies offering driver on demand service in several locations. This actually provides a driving service to car owners who needs a driving assistance for a certain time. It's good that there's a similar service offered in my area and I've heard a lot of positive feedback about it.

Anyone here who tried on availing a similar service? How was the experience? Also, does anyone want this kind of service to be offered in their location?
