My own theory is almost the same, except it's the "last half mile" which
is the killer. In cities, the ever increasing pedestrianisation, one way
streets and anti-ratrun measures, often make it virtually impossible to
get any closer without detailed knowledge.

That's fine as long as you don't end up a hundred yards the wrong side
of a set of "buses only" bollards, or similar feature.

In a recent discussion of Cambridge, it transpired that to get to the
other side of one similar "obstruction" required a two mile diversion
using exactly the correct roads at every junction. Although maybe a
satnav wouldn't necessarily be up to date with all the "no left turn
except..." and other anti-ratrun devices either (many of which the
Google Streetcar seems to ignore!)

Yeah, I've been fooled in Cambridge many times. Always take the wrong
turn. But now I just dump the car in the multi-story and walk.

You'll have been one of those parked in a bloody awkward place while
trying to get an old lady to give you directions to a chemical factory
or similar. Meanwhile blocking the free flow of traffic along the
road while other road users negotiate their way around the blockage
you were causing which in itself introduces the possibility of other
hazards.
20 years ago it was a necessary evil rather than drive around getting
lost. Today it is just the actions of somebody being selfish.

Ah, a luddite.

If the satnav breaks down, then you would resort to navigating by the
same method you would have to use if you didn't have a satnav in the
first place, or course.

Whilst getting to any town or city in the UK is pretty easy, a satnav
is invaluable for getting you to a particular street once you get
there. It is generally far safer and quicker than a map if you don't
have a passenger to do the map reading, especially if a blocked road
means that you suddenly find yourself needing to take a different
route to the one you planned.

Getting back home again is generally far easier, because there will be
signposts directing you to major roads and towns.
