I had the same problem when I first started. It seems that people enjoy overcadeing just in case a mob of several hundred zeds come out of no where. You definately want to get freerunning ASAP. That made life at least liveable. Esp with people cadeing PD's and Hospitals to EHB when the people that need them the most, Newbies, can't get into them. I think maybe some of the barracade plans need to be revised to make things a little nicer for the new people? Just a thought people.
