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. -- Roland Perry

E.g. two roundabouts then a school, a railway bridge etc. 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!) -- Roland Perry

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. G.Harman

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. -- Cynic |
