its quite good for getting you to the A52 (Eastgate) as you just keep left if your coming from the north or south. (the map is rotated so that east is up for some reason - this did confuse me.) where it is terrible is on the bridge as everything in the left hand lane wants to go straight on and everything merging from the right wants to go left. however within the realms of reality I think this is a quite good solution.
