Your comments are much appreciated as having accurate data on the site is very important to us. Having investigated the issue you reported, we have identified a potential data anomaly. Our data comes from various suppliers and we have forwarded your query to the relevant supplier in order for them to investigate and make any necessary amendments at source. We receive regular data updates and although we are unable to give you a timescale of when this improvement will take place, you can rest assured that any corrections will filter through to the Multimap website in due course.
OK, here's another rather more humourous "anomaly". I entered a postcode to get a map. The correct map came up (surprise!). I then clicked on directions thinking it would use my map position as the starting point. I then entered my destination postcode. However, the initial postcode location wasn't populated from the map search, instead it was blanked off and the "default" postcode used instead. Not content with using the point in London where all distances are measured from, namely the equestrian statue of Charles I at the south end of Trafalgar Square (the original site of Charing Cross), multimap has its own central point of reference.
The actual centre of Multimap's universe is show on the following image (click to enlarge), taken from a screen capture and easily replicated via the above steps.
So now we know from the enlarged image. Not only is the centre of the multimap universe a gentlemen's private part just off King Willy (sorry William) Street, but on a journey to what should be the centre of UK mapping it sends us past Nelson's column and Cockspur Street (that's enough genital references) in a convoluted path apparently going the wrong way down a one way street between stages 3 and 4. All in all, rather a cock up.
I think that the orange advert says it all: "When turning back is out of the question you have to put your trust in what you know". Which is this case is knowing that multimap once again is not the dogs bollocks, rather it belongs in King William's toilet.
