The 80/20 affordance set to me is something like: - I can break a route into segments. - Segments modes can be chosen, or the fastest (or some other metric) one is computed. - Segment routes might be manually entered (waypoints) or computed. - Arbitrary sequences of segments can be strung together, whether automatic or manual. - Can ask for a whole trip to be computed to start, and then "sculpt" it by splitting it into segments I can modify (manually override, change modes, etc). Maybe one day I'll try to whip something up that matches what seems would work to me. I get the sense this kind of tool might be like knowledge management tools where there's no one size fits all solution.
