Recently, it's felt that Apple's plans for an autonomous car - dubbed 'Project Titan' - were fading with the tech giant losing staff to other carmakers, and reports suggesting that there was little faith for the project within the company.

Now, in a letter to the U.S. National Highway Traffic Safety Administration (NHTSA), Apple has urged the government to encourage companies to test self-driving technology on public roads. This all but confirms that Apple are working on an autonomous car, or some form of autonomous technology.

In the letter, Apple says:

Apple uses machine learning to make its products and services smarter, more intuitive, and more personal. The company is investing heavily in the study of machine learning and automation, and is excited about the potential of automated systems in many areas, including transportation.”

An Apple spokesperson said, “Apple is investing heavily in machine learning and autonomous systems”.

So, will we see an Apple test car on the roads soon? Or will Apple team up with other carmakers and simply make the technology that those vehicles use? Hopefully we'll know more soon, but at least we know that Project Titan isn't dead.
