I started my morning by researching ways to draw down with ride sharing. Turns out smartphones allow people to share real-time information about where they are and where they need to go, social networks are buoying trust, so individuals are more likely to hop in with someone they have not met, and the algorithms behind it match them with others and map the best routes improving daily. When cars are used collaboratively you can see fewer cars on the road, but when fuel is cheap, carpooling declines, and there is a desire for autonomy, privacy and expedience.
