It moves the topic away from Symbian somewhat (at least for now, but there is no practical reason it can't feature on a Symbian Device in future).
But what you are ACTUALLY talking about Steve, is not so much Sat-Nav "Artificial Intelligence", but real driver "Actual Experience History".
Enter, TomTom IQ Routes...
Explanation: The now being released TomTom x30 Series of standalone PND devices, include a feature called "IQ Routes". In reality what this actually is, is HISTORIC, real world, user supplied data from us lot that have been giving this to TomTom anonymously without realising what they were building it all up for, these past however many years.
It is actual data for time taken to travel routes and roads, and TomTom uses this instead of a simple stated speed limit value for the roads in question.
Thus, depending on the day of the week, weekend etc, when you travel, different routes may be supplied - in your example Steve, on a quieter weekend, with perhaps less traffic on the main motorway, IQ Routes perhaps, for SOME motorways, knows that these are still the quickest route.
However, rush hour during the week, the real actual historic data it has will tell it that the motorway is log-jammed and will take forever, and thus local roads and junction hopping etc will be quicker.
That is the THEORY anyway... So far it's way too early to report on how well or otherwise this works. But at least the PRINCIPLE is sound.
Certain short-comings for now even with this approach, is that it only lets you specify the DAY to be travelled, not the time, so can't differentiate between a rush hour jam, and a mid morning flyer.
But it's a START towards reaching the level of proper reliance on sat-nav that your article talks about.
Couple this with TomTom HD Traffic - again real-time traffic info supplied by users that actually have a special vodafone sim card and data connection with the device, and you can measure the REAL time taken, in real time (if that double usage didn't confuse you) to travel a set distance. And measuring against cell location or gps location triangulation, it can ascertain instantly, in real time, if there is a problem, with lots of users taking longer than it should for them to traverse a certain route.
This is a two way data path, so the results can also in real time, be transmitted back as RELIABLE traffic data, for sat-nav users receiving it.
Again, this sounds wonderful, whilst the reality will likely not be as good as this at first.
But nevertheless, BOTH of these new approaches are (pardon the pun) driving towards the reliable, useful, sensible level of sat-nav 'intelligence' and worth, that your article hints at.
And whilst it is TomTom that are spearheading these two new approaches, it is not entirely unique, other companies are looking at similar things, and as far as I know there is no patent as such, on the general idea behind them.
So eventually we should see this sort of approach becoming the norm for all sat-navs one day.
But to me, FOR NOW Sat-navs are a GREAT tool to get me to somewhere I don't know how to reach, or where it is located.
But they have never been a tool for getting me there the QUICKEST way, as invariably, local knowledge will always produce a better local route. A sat-nav is just an ideal tool for if you don't even know how to get to a place.
In time, with the sort of things outlined above though, this might actually change!
