Tesla CEO Elon Musk got us all wound up a few weeks ago with a tweet about showing us his "D."
And we all had a nice laugh. But it turns out the "D" in question stands for "Dual-motor," and is a feature on the new version of Tesla's Model S.
The S P85D give the front wheels more power with additional electric engines. Most excitingly, however, was Tesla's demo of the P85D's auto-pilot, which takes control of the company's fastest car ever.
As Slashgear explains, however, the auto-pilot isn't the same technology as Google's self-driving car and won't just take you from Los Angeles to San Francisco without you, the driver having to pay attention.
...the Model S won't drive itself and allow you to take a nap in the back seat, but it does have a smart lane-change system which will automatically move across a lane when you hit the blinker - assuming there's nothing already occupying it.
The sensors work all across the car's speed range, and can spot everything from other vehicles through to softer objects like a runaway child. Meanwhile, cameras that track road signs will be able to identify the current speed limit and adjust the cruise control to match.
By the way, you can't buy this car. It's not out until February 2015. Oh, and it costs $120,170.
