Tesla has a huge incentive to deploy self-driving tech. But is the world ready?

"Bryant Walker Smith, a law professor at the University of South Carolina who specialises in autonomous driving, agrees.

"The technical definition of 'full' means I can get into this car, fall asleep, and (the car) can take me from downtown Manhattan to the mountains of Maine in the wintertime," he said. "The concern with language like 'full self-driving' is that people will be too confident in the technology" and the industry "will lose credibility and trust.""
