Howabout,
I've been rummaging through my supply of analogies and metaphors and the best I can come up with is ...
The Brisbane Airport Roundabout .... God bless it ...
The Roundabout was not working... too many prangs and delays ...so they added Traffic Lights to it ...WTF .... "we'll make this sucker work, no matter what!"
It didn't .... they are now completing a flyover ...
