Tesla's newest all-electric car has a button on the dashboard labeled "INSANE"

(WITI) -- Tesla's new Model S P85D all-electric car is something special. One of the more interesting features -- drivers can select between two acceleration modes. One is labeled "SPORT" (which is typical of sports cars) -- and one is labeled... "INSANE."

Just watch what happens when the "INSANE" button is pushed during test drives.
