Interesting idea. Just a few questions, so I can understand better:

1) 200,000 mobile weather stations--how do these function? What's the coverage like in any given area? How up-to-date is the app; if I'm driving in the middle of nowhere in southern Illinois, is this going to be accurate? Does the app update conditions in realtime?

2) It seems to me that the two weather parameters that will affect fuel economy the most are wind and temperature. These don't vary much over even a large area of the country on any given day. What benefit will I derive from the app that I couldn't get from checking weather conditions online before I leave on a trip and adjusting my route accordingly myself?

3) On a similar note, if I'm traveling between two fixed points, how much are the details of my route going to matter when I'll have to travel roughly the same distance against a headwind, or with a crosswind, or a tailwind--i.e. in the same general conditions? Do you have any metrics yet on how much fuel this could save?
