When you get behind the wheel of Tesla's latest electric car, the Model S P85D, you get to choose between two modes for the vehicle's acceleration: "sport" and a faster option called "insane."
How insane is insane mode? Pretty insane, as illustrated by the shocked reaction of these passengers in a video from DragTimes. Tesla says the P85D can accelerate from 0 to 60 miles per hour in as little as 3.2 seconds.
