Jack Stewart meets the engineers who are building vehicles that drive themselves. He has a ride in Google's driverless car, which has no steering wheel and no pedals. Google's Chris Urmson explains the company's approach to autonomous vehicles.



Jack visits Stanford University's driverless car project where professor Chris Gerdes shows him Shelley, an automated Audi that races around a track at speed as well as a human driver. Chris is collaborating with a philosopher to explore some of the difficult questions around autonomous vehicles, such as who is liable if there's an accident. Is it the human or the car? And ,Jack meets Josh Swirtes whose company, Peloton, is linking trucks together with the idea that they should have fewer accidents.
