Only a tangent, but I just started a new job and used Google Maps to find me a route and it's absolutely glorious. It's on roads I never would have thought of, avoids streets with heavy traffic, only has 3 traffic lights.. I'm not sure if it's just dumb luck, or the fact that there are a decent number of neighborhoods through Palo Alto that are relaxed tree-lined streets, or what.. but it's only a couple miles shorter than my commute to my old job and an order of magnitude more pleasant. Looking forward to using this API to see if it recommends changes.
