Letter: Upside down map-reading

Sir: Your report (6 April) on the first of a series of Ordnance Survey maps designed for cyclists explains that it was made possible by the "sophistication of its computer mapping techniques". While applauding this venture I had hoped that OS would by now have employed such skills to repeat on the back of their maps the same area but with reversed legend so that south is at the top. It would make driving down from Scotland and up to Hampshire so much easier without standing on one's head in the car trying to transpose left and right.
