Google Maps UK

Google Maps has been launched in beta for the UK and seems to be potentially useful (although I’m not sure about the map on the launch page, which shows the position of Great Britain relative to Newfoundland!). However, a quick look at Ruralville revealed several roads depicted on the map that simply do not exist (they are either footpaths or private drives and farm tracks – I looked at some nearby MoD land on the map and found tracks displayed that are definitely off-limits).
I’ve also tried the driving directions feature, using the journey between home and my parents as the test. It seems that Google doesn’t know the difference between "left", "right" and "straight ahead" – there are several glaring errors in the directions offered to me. I’ll stick to the AA driving directions qwhich are generally accurate, even if their journeyt times are almost always hopelessly optimistic.
