Because we wants it...
I have a Sony CrapNav and it never works with postcodes. It also has a fixation with a section of Leamington Spa, that despite asking it to recalculate the route kept taking me back to a junction on a closed main road. It also overshot Manchester completely and took me back down to it via Glossop, after taking me on a RAC rally through small villages that looked like something from Lord of the Rings, where about every 100 yards were speed cameras and tractors towing trailers of hay, oh, then came the rain. I hadn't a clue as to where the hell I was. I hate it and I suspect it knows!
