Pam Fletcher, executive chief engineer of autonomous tech at GM, would not share specifics about timing, but she did say the company’s first fully autonomous car will be available via the ride-sharing service sooner than you may expect.”We have not made that announcement yet, but what I would say is this is all coming much faster than people anticipate, so I’ll say that much. We have been transparent about that,” she said. “We are working on an on-demand ride-sharing network with Lyft, it’s not something we are thinking about, it’s something we are very much readying for consumer use.”
