From the Youtube video description:

Terrible day at the Lake. Chevy Tahoe goes into lake. The audio says the car was left in reverse. That was said on the spot before I knew the details. Tahoe owner said the truck was in park. Video starts with the Tahoe coming out the first time. A nice passerby hooks up a ski rope and a tow strap to pull him out. As soon as it is pulled out the rope breaks and it goes right back in as seen at 1:10 in the video. It made for a crappy day for this fellow and his wife. Thank goodness the family wasn’t in the car and nobody was seriously hurt. The guy who owns the Tahoe was treated for hypothermia. The Chevy Tahoe was totalled, as you can guess.
