Pack mentality in general - people who are brave in a group but not when they're by themselves.
We were commenting about this yesterday at work, I work beside Phoenix towers on Customhouse Quay, and watching out the window at the junction of Hunter St and Customhouse Quay, and again at Post Office Square and Customhouse Quay the number of people crossing the road thinking that because they are in fancy dress traffic should stop for them. You know what the traffic is like at times hooning along hunter st, having to slam on the brakes at the Junction of Customhouse Qy because a bunch of oompa-loompas counldn't be arsed for the green man before crossing.
