If everyone takes the local "shortcut", and jams it with so much traffic that it takes 10 minutes longer to get to your destination, it's not really a shortcut. Amirite? Do you have this type of shortcut in your town?
There's a shortcut that goes past my house. It's bumper to bumper almost always, while the main road is mostly clear, because everyone is on the "shortcut". Yet drivers think they are still taking a shortcut.
