What robots driving cars can tell us about artificial intelligence. Ed Butler speaks to Bryn Balcombe, chief strategy officer of the autonomous vehicle project Roborace.

Yoshua Bengio, professor of computer science at the University of Montreal in Canada, gives a defence. (Photo: A Roborace robot-driven car in action on the track, Credit: Getty Images)
