In 2011, we learned that even our cars and trucks were going "social" when Salesforce.com announced its partnership with Toyota. However, the social capabilities of the partnership were limited in scope (car diagnostics, tune up reminders, etc.). What if your car could prevent you from driving a certain route because it knew what areas were traffic-heavy? That car sounds "social" in a fuller sense; it might be possible with the new Beat the Traffic API.
Google has added one of the most popular features of its consumer Google Maps product to the Google Maps API. Predictive travel time is oft-used by consumers to find best routes, and avoid traffic. Now, developers have access to the feature and can integrate the functionality into third party apps.
