I am the first to admit that all Government databases are doomed to failure from the outset, however, the only solution that I can see is for Ordnance Survey to A) operate a change management system, which requires all local authorities notify them of changes to roads before they happen. B) Ordnance Survey should be government funded so that their data can be put in the public domain.
I don't think that sort of system would add much of an overhead, surely councils need to maintain systems which detail their roads and associated width, height, speed restrictions. If the ordnance survey information was freely available, then we wouldn't have to deal with the crap data we get from Tele-Atlas. It would, also mean that in theory all sat nav updates could be free. Personally I think that it should be a legal requirement for sat nav companies maps to be correct and update their maps and for drivers to update their sat nav every couple of months (if only on the grounds of safety).
BTW, Tele-Atlas provide most maps for SatNav (they are probably cheap than OS) - which is probably why you find that roads which are less than 5 years-old don't appear on your brand new Sat Nav but do appear on your 3 year-old road atlas (most of which use OS data).

Yes and that is what Sat Navs use. If you are referring to road atlases, I don't know if you have noticed, but they don't include much by way of width/height restrictions (the point of the article) - that is mostly down to road signs

TomTom, for one, actually provide that in their latest devices, by way of MapShare. With regard to your point about the petrol station, that is down to your Sat Nav's points of interest database (not it's map), which on most Sat Nav's has been user updatable for a long time. Personally I don't see why users should have to tell TomTom to update the maps, TomTom should be able to get free information about roads well in advance of them being changed - after some has to plan and keep records of changes to roads, they aren't organic lifeforms (the same goes for road works).
