Apple hints that self-driving car rumors may be true in recent letter to NHTSA

"Should it begin experimenting with driverless technology, Apple would join companies including Google, Tesla, Uber, and Intel in the autonomous vehicle market—which is not a surprise, according to Bryant Walker Smith, assistant professor of law at the University of South Carolina and expert in the autonomous vehicles space.

"Companies like Apple, Google, and Amazon want to be ubiquitous in our lives," Walker Smith said. "For better or worse, driving is a big part of many people's lives, so I'm not surprised that Apple is exploring the car as another device or at least as another space. We'll likely see some interesting partnerships in the next few years as companies combine their strengths.""
