THIS IS HOW quickly transportation has changed in urban America. In July 2010, a service called UberCab went live in San Francisco—that’s fewer than eight years ago. Washington, DC’s Capital Bikeshare, the country’s largest bike-sharing program, really got off the ground in 2010. Austin became the first US city to host car-sharing service Car2Go a few months into the same year. Lyft launched in SF in June 2012.
That’s a ton more travel options in a short time, most of them enabled by the explosion of the smartphone and fostered somewhere in the Bay Area. Some have indubitably made it easier, cheaper, and safer for residents to travel through dense cities. But for city governments that feel responsible for getting all their residents around, the sudden burst of diversity has confused the whole picture.
