I think car sharing is important to transit orientation. Because automobiles will always be a useful tool in the transportation toolchest, having available cars for people who need to run an errand or go out of town to an area not served by transit is great. It also cuts down on needed parking spaces and creates an environment for using transit as a main mode of transport. I'm not quite sure what the merger means but other folks have been covering it so I'll let them do the commentary.
