Driver On Demand

It has been a month that I've been seeing people talking about the driver on demand and their experience upon availing the service. I've haven't really tried using it but I think I will try soon especially that I will be attending several conferences in a day. Also, been seeing that they will be expanding the availability of service to several location which is a great news!

Anyone here already tried a similar service? How was the experience?

Also, would you want this kind of service to be available in your area?
