My mom always warned me not to get into a car with a stranger. I can’t imagine her reaction if I made a habit of getting into cars with groups of strangers. But that could be the next big thing as both Uber and Lyft have announced carpooling services aimed at filling the backseat with other folks going your way. I thought the whole point of technology was to allow us to interact with others without having to share our personal space?

+ Sometimes a crowded commute can be beneficial. In Perth, a large group of passengers helped free a man who was wedged between a platform and a train. (Great. Now my mom won’t let me take trains either…)
