BMW revealed an augmented reality glass that turns anyone into a fast thinking mechanic. The video posted below shows when you wear the said glasses, and designate a part that needs to be removed, they will start highlighting what needs to be taken apart in order to reach the problem.
It will also show the right way to do things, and instructions can be audible too. Even if you're a noob, you might just able to tinker with your car's engine properly. Check out the video below. It's been six years since they first released this video. How far along have they come?
