I don't know anyone involved personally. but I'd say they have done a terrific job. finding the bike-Denver map, after having made the trip to work based on google maps bike route, was big difference. i think it added maybe a mile, and technically backtracks a little, but the quality of the roads when i got on the cities route combined with less stop lights i'm actually making it in the same time or less
