Our cities are making us – and the planet – sick, and the problem lies in the automobile, which has taken over how we live and use space. Thankfully, new technology like autonomous vehicles and 3D printing has opened the door for us to bring our cities back from the brink, says transportation expert and city planner Gabe Klein. But we need to act quickly to ensure cities will be places we want to live.

Gabe is the former Commissioner of the Chicago and Washington DC Departments of Transportation. In both cities he revamped technology platforms and government processes while focusing on putting people first vs. automobiles on city streets. This included launching two of the first and largest bikeshare systems in the U.S. and building protected bike lanes and better pedestrian infrastructure for vulnerable citizens citywide, as well as facilitating private services like carshare and rideshare that could help each cities mobility goals.
