Apple is apparently much further along in developing a self-driving car than many people thought, reports the Guardian.
In May, Apple engineers discussed the possibility of using GoMentum Station, a former San Francisco naval base that other Silicon Valley players use for autonomous vehicle testing, according to documents obtained by the Guardian under a public records request.
A message from one Apple engineer reportedly stated, "We would… like to get an understanding of timing and availability for the space, and how we would need to coordinate around other parties who would be using [it]," according to the report.

Apple declined to provide comment to CNBC. GoMentum Station did not immediately return a request for comment.
The 5,000-acre GoMentum Station is one of the largest test facilities in the world, according to its website, which boasts that "several automobile manufacturers will test and validate their [autonomous vehicle] technologies at the GoMentum Station..."
Video from the test facility's website shows a self-driven Acura RLX navigating the 20 miles of paved roads in an eerie abandoned environment.
Apple has yet to publicly acknowledge it's developing a car, but the company has led many to believe exactly that.
The tech giant has already hired auto industry executives, including Fiat Chrysler's Head of Quality Doug Betts, and just a few weeks ago, Apple CEO Tim Cook reportedly toured a BMW production line in Germany.

In response to fielding questions at this year's Code conference over whether Apple was developing a car, Senior Vice President Jeff Williams noted that "the car is the ultimate mobile device, isn't it?"
"We explore all kinds of categories, and we'll certainly continue to look at those and figure out which ones are ones where we think we can make a huge difference."
