TRI CEO Dr. Gill Pratt presents at the 2017 CES

Highlights of Dr. Gill Pratt's remarks during the Toyota press conference at the 2017 CES:

  • "How safe is safe enough? Society tolerates a lot of human error. We are, after all, only human. But we expect machines to be much better."

  • "What if the machine was twice as safe as a human-driven car and 17.5 thousand lives were lost in the US every year? Would we accept such autonomy? Historically, humans have shown nearly zero-tolerance or injury or death caused by flaws in a machine."

  • "None of us in the automobile or IT industries are close to achieving true level 5 autonomy. It will take many years of machine learning and many more miles than anyone has logged of both simulated …and real-world testing to achieve the perfection required for Level 5 autonomy."

  • "Considerable research shows that the longer a driver is disengaged from the task of driving, the longer it takes to re-orient."

  • "It is possible that level 3 may be as difficult to accomplish as level 4."

  • "There is evidence that some drivers may deliberately test the (L2) system’s limits…essentially mis-using a device in a way it was not intended to be used."

  • "Human nature, not surprisingly, remains one our biggest concerns."

  • "There are indications that many drivers over-trust the (L2) system."

  • "When someone over-trusts a level 2 system’s capabilities they may mentally disconnect their attention from the driving environment and wrongly assume the level 2 system is more capable than it is. We at TRI worry that over-trust may accumulate over many miles of handoff-free driving."

  • "Paradoxically, the less frequent the handoffs, the worse the tendency to over-trust may become."

  • "TRI has been taking a two-track approach, simultaneously developing a system we call Guardian, designed to make human driving safer…while working on L4 and 5 systems that we call Chauffeur. The perception and planning software in Guardian and Chauffeur are basically the same. The difference is that Guardian only engages when needed, while Chauffeur is engaged, all of the time during an autonomous drive."

  • "In Guardian, the driver is meant to be in control of the car at all times except in those cases where Guardian anticipates or identifies a pending incident and briefly employs a corrective response."
