What criteria does the software use to calculate vehicular routes? If
there is a place to set these options I haven't found it. On longer
routes it does not seem to pick the shortest or quickest way. In my case
it routed us on interstate, but I take it that was not the case in
Dave's case. Near my home on short routes it keeps us on side streets
longer than necessary, with more turns, to use a particular main street
instead of just turning onto another main street from the street where
we live. The routes work. Sometimes they just don't make sense.
Clarification will be appreciated.

Hey rob, I agree that it takes forever to search for a city within a
state,
especially if the city is not close by. In exploring your search, I
started
In San Francisco because I knew you wanted to start outside of Oakland,
but
they are right next door so I didn't encounter that problem.
In future releases it would be nice to be able to search for a city, as
you
suggest, or even a state, without having to know street names or
addresses.
I think that seeing a difference of mileage to various areas is common.
Recently I did a route from South Bend Indiana to Cincinnati because we
are
going to be traveling that route this summer. There were two ways to
travel
that were recommended to me by friends, but the GPS chose a third way,
which
was about fifty miles longer than Map Quest. It also chooses a longer
and
more circuitous, but perhaps much more scenic, route through the
mountains
from where I live to Prescott Arizona, but it would get you there. I
think
that while playing with maps and longer routes is fun, the true
usefulness
is in short routes. It is designed primarily for walking and does a
heck of
a job in that regard.
I believe that the true accuracy is in marking way points and POIS. For
example, I can stand in front of my house and if I check the address, it
will tell me I'm two blocks away. This was true with version 3.3 and is
true with 3.5, and I don't realistically expect it to change. I think
it's
in the inaccuracy of the maps and there isn't much that can be done
about
it. However, once I made my home a POI, it works flawlessly by telling
me I
am home when I reach my driveway.
A couple of days ago I was traveling and stayed in one of those motels
with
outside entrances. I found that by marking my building and my room, I
could
travel quite flawlessly around the complex with little orientation.

taxation WITH representation isn't so hot, either!
