In this photo taken Wednesday, May 14, 2014, Google team members pose by a Google self-driving car at the Computer History Museum in Mountain View, Calif. From left is project direct Chris Urmson, Brian Torcellini, Dimitri Dolgov, Andrew Chatham and Ron Medford, the director of safety for the project.
