The rumor mill is turning but Apple car details remain vague

The main topic of that discussion was the regulations the department is working on for allowing autonomous vehicles on the road but this still isn't proof that Apple is working on a self-driving car. (Video via Delph Auto)

But don't expect the company to start talking about it anytime soon. Apple's not exactly the most open company around.

"When he was here, he said Apple is working on a driverless car," said Stephen Colbert on the "The Late Show."

"I've read that," said Apple CEO Tim Cook.

"You guys aren't big on secrets, tell me about it," said Colbert.

Still, we can't help but wonder what an Apple Car would be like.

Google went very non-traditional with its model; making it a very-compact, two-seater without a steering wheel. Will Apple also challenge the traditional model for cars?

Another big question is how Apple would handle manufacturing. A hallmark for Apple has always been they design both the software and hardware for their devices.

But a vehicle is likely to be a bigger endeavor than a smartphone. Maybe this turns into an extremely rare instance of Apple partnering with a manufacturer.

Whatever Apple has planned, they are likely pretty far behind the pack. Several other companies have been pretty open about their self-driving car efforts, especially Google. That company has logged tons of test hours on California roads and recently began testing in Texas.
