UBD being a commercial company makes no secret of the fact that they
have about 12 errors per map in their directory - these exists soley to
catch anyone breaching their copyright. Also the data is adjusted for
map presentation - not on road use.

Essentially UBD = Gregory's = Pacific Access = WhereIsIt = Yellow Pages.
They see in car navigation systems as being one of the big future
markets.
