The following thread in the business section got me thinking? How many providers use drivers? Also what is the view of providers who have drivers?

First thing that comes to mind for me is Pimp! While it may not be necessarily true IMO that's the perception it gives off. I've never met a provider who doesn't have her own method of transportation and if I did, I'd probably cancel on her just as a side of caution.
