Maybe we should have a GPS-Off. Set a few tricky routes, and then see
how much the brands/maps/methods vary.

Eg, for no good reason I just picked a trip from Warrnambool to
Benalla (looked like it had a few options!)

Using IGO 8, Sensis maps, and only the Short, Fast, and Economical
methods (it has more..):
Times and distances:
Short - 6h16m, 441km
Fast - 5h28m, 457km
Eco - 5h31m, 450km

The short route was Mortlake, Lismore, Scarsdale, Sebastopol,
Ballarat, Daylesford, Tylden, Woodend, Kilmore, Bradford, Euroa,
Baddaginnie (!), Benalla.

The fast route was Camperdown, Kariah, Duverney, Geelong, Princes Fwy,
Western Ring Rd, Hume Fwy, Euroa, Midland Hwy, Benalla.

The economical route was very similar to the fast, some minor
differences around Melbourne.. All seemed to make sense to me....

I also tried that Chinkapook to Hopetoun one and it chose straight
down to Sea Lake, cut across on a sort of diagonal back road route to
Lascelles, then B200 to Hopetoun. Again, that looked correct
according to the printed map I have.

Clearly I have no life...

I just tried the same thing with the TomTom 730 (navcore 9002 map version
845.2661)

Short - 5h25m - 430km.
Fast - 4h45m - 455km
Eco - 4h45m - 455km.

Interestingly, it considered the fastest route to be the most economical and
reported exactly the same time for both. Whether this is accurate or not I
can't tell you as I've never driven this route before, but past experience
has shown this machine to be very accurate with time estimates and usually
down to the nearest minute.

Clearly, I have no life either.

I had to look up my work diary and the job was in 10/2008, I can't find
the exact address but you are right its not even 80klm from Hopetoun and
not all that far from Lascelle, it just seemed to be a long way from
anywhere but I remember being surprised that the GPS found the place so
easily.
I do remember that the customer's kids had a pet kangaroo that followed
them around like a puppy:-)

Local knowledge would mean that as soon as you got to Kilmore you would
use the Hume Freeway which bypasses those 3 towns.

Most GPS's assume is that the road is clear of major traffic hold ups,
at peak times of the day when the Western Ring Road and other Melb roads
are very slow the shortest route could also be the fastest because it
avoids Melb.
Having been to almost every place on either route recently I know that
the shortest route is also a more interesting drive.
I like my GPS but like John H says local knowledge is a big advantage.

Now that's an interesting one. Despite having 'unpaved roads' turned
on, you're right - IGO/Sensis at least, does *not* want to go that
away. Are there any roads in the short route that might be classified
as dangerous/seasonally impassable, 4wd only, maybe? I'd like to find
out more about the reasons why.

Might try experimenting, to see if there's a clue about *where* it
gets the idea not to go thataway...
