Oh, ok, I only mentioned that because my first (autorouting) GPS, the
Garmin GPS V had very basic mapping for the whole world built in then
you added more detailed maps for the areas you were specifically
interested in. I think mine was 'Base World Map + Europe (down to
house level) so if you drove 'off the detailed map' (and I have) you
could end up with just the basic stuff?

Most likely just an error in the mapping data
that has never been corrected.

I've just checked the map on TomTom's error reporting site and it
looks like it's correct there. So, maybe the 'foreign drivers are just
running old / un-updated versions or really aren't reading them
properly?

Getting errors corrected on satnav routing info is a pain.

There's an unmade road near my parents' holiday cottage in Yorkshire, with
very tractor ruts and huge boulders sticking out of it. You wouldn't get a
4x4 up it and even tractors might have ground-clearance problems.

It has been closed to through traffic as long as I have known it (1970s)
and maybe for a lot longer than that.

However a lot of satnav sites still list it as a through route and try to
route you that way. I went on to TomTom's site and a few others and
reported it as a dead end farm access, but when I checked a couple of
years later it was still showing as an available route. I believe one of
the satnav sites now shows it as being closed.

Try it with google.maps They have fixed
plenty of stuff like that very quickly for me.

Not Apple maps tho, they haven't changed a thing I have reported as wrong.

It's a shame that the road *is* closed because it would be very useful for
knocking several miles off the journey from the village to Richmond and
the A1

When satnavs first came out they used to show access onto the A34 near
where I lived in Oxfordshire via a junction that was either closed several
decades ago or was planned but never built (I could never find out which).
I remember seeing an HGV that had got stuck trying to do a U turn at a
mini-roundabout in a nearby village after it had taken the route thinking
it could get onto the main road and then tried to turn round at the next
village afterwards.

The perils of HGVs with inadequate satnav software (ie without HGV
restrictions) is demonstrated by that train crash the other year in
Hampshire where an HGV missed a turning and tried to take the next road,
realised that it wouldn't get through a narrow bridge, tried to reverse
and knocked the bridge parapet onto the railway line where a train hit it
before the message got through from the local 999 operator to the train
driver. The message-passing and accident-reporting procedures came in for
a lot of stick in the official report because the bridge didn't even have
a "phone this number if a vehicle hits this bridge" sign on the grounds
that it was not a bridge which had a history of problems (whatever
happened to "there's always a first time"?)
