Whose hands will be on the wheel of the automobile of the future? If we are to believe many experts and entrepreneurs in the burgeoning mobility industry, it may be no one’s.

But how safe are driverless vehicles and how close are they to ruling the road?

Tonight on PBS, “NOVA: Look Who’s Driving” peers under the hood of the autonomous vehicle industry to investigate how driverless cars work, how they may change the way we live, and whether we will ever be able to entrust them with our lives.

After years of anticipation, autonomous vehicles are now being tested on public roads around the world. Dozens of startups have sprung up alongside established auto and tech giants — which are also testing the waters — to form what many hope will be a transformative new industry.

But as innovators rush to cash in on what they see as the next high-tech pot of gold, some experts warn there are still daunting challenges to overcome—like how to train computers to make life-and-death decisions as well as humans can.
