Apple is the latest company to jump on the self-driving bandwagon. Rumors have been circulating about Apple’s self-driving electric car, codenamed Project Titan, but according to documents obtained by The Guardian, the company is a lot further along in its development than expected.

There still aren’t any specific details about Project Titan, but The Guardian reported that it is almost finished, and Apple is already looking for a space to test it.

Correspondence obtained by The Guardian revealed Apple had plans to visit the GoMentum Station, an old naval weapons station where companies like Mercedes-Benz and Honda have tested their self-driving vehicles.

“We had to sign a non-disclosure agreement with Apple,” Randy Iwasaki, owner of GoMentum Station, told The Guardian. “We can’t tell you anything other than they’ve come in and they’re interested.”
