That feature is the only way to force the routing go via the route that
you know to be best from your knowledge of local roads and conditions.
I guess that's what I meant with "route planning", to my way of
thinking a journey only has 1 destination but multiple paths to get
there. Not strictly true for the delivery man model I guess.
I was not sure about that. There are some GPS receivers or softwares that will let you plan and save a route without a fix or in an "off line" mode and some that won't. That is sort of what I think of when I read route planning.
There are also some models that simply won't let you add any intermediate destinations to a route or maybe only a single intermediate destination. Those are unsatisfactory. And there are some that have a feature usually called a "detour" that is, in fact, no more than a change in the destination and of little use in controlling routing.
In my Ottawa to Miami example, if the software allowed me to block off
the metro DC area with an "avoid" it would be slightly better then
making me pick Charlette NC as a "via", as it would require less local
knowlege. Either way as long as I can do it from my living room before
the trip and let me pick that route up again in the motel parking lot
part way down..
I agree with that when it works. But in the long run you are still letting the GPS decide the routing around the avoid so you don't know what you will have until you see the result. If the result with the avoid is still is not what you had in mind, then you're back to needing to use the via points to get it right. So I've evolved to a process of picking the start and finish, looking at the result, then adding via points until it gets it right.
If the DC area has not changed, people will get in fistfights over whether it is best to pass east or west of the city for any given time of day or day of the week. Fortunately, I've not been there in some years.
Logical routing would seem to have you staying farther West on I-81 anyway. If it wants to get you over to I-95 too far North it is an invitation to disaster. I'd hold off on moving back over towards the coast until I-64 or, even better, I-77. That spectacular run down towards Winston-Salem and Raleigh has to be seen to be appreciated.
No GPS unit is ever going to have the intuitive knowledge and experiences of a human to get routing right except occasionally. Only a person who is in total ignorance of the real world would use some of the routes offered.
I live east of I-95 in Maine and every program I've ever seen wants me to go through New York City and use the New Jersey Turnpike to get very far South. By adding a mere 30 to 50 miles or so to the journey, I get further West sooner and have a much more pleasant trip.
