I used to be in the habit of always putting my route in so I'd know when I
should arrive.  With the garmin, I'd add way points along the way so I
could force back roads, avoid intersections in busy areas w/o lights, etc.
I can't do that w/ the car GPS but I can say avoid 495, avoid rt 3.  I
preferred the garmin way.  It'd be nice to have both.

Waze also wants user input about slowdowns, accidents, in route timing and
other user reported info.  You can't do that w/o data access.

FWIW - has anyone worked on TCP over text messages?  If they can do it over
carrier pigeons...
