A Tesla Cybertruck took an accidental swim in the Ventura Harbor on Monday, prompting a multi-agency response to carefully retrieve the electric vehicle from the water without sparking a toxic battery fire. Tesla founder Elon Musk tweeted in 2022 that the Cybertruck "will be waterproof enough to serve briefly as a boat, so it can cross rivers, lakes & even seas that aren't too choppy." This truck, however, quickly sank in 8 feet of water, said Carson Shevitz, captain of TowBoatUS Ventura, who helped coordinate the rescue. Ventura Port District Harbor Patrol officers spotted the truck bobbing by the boat launch ramp shortly before 11 a.m. , Shevitz said. The driver told Shevitz that he meant to put the vehicle in drive after launching a Jet Ski but accidentally threw it in reverse, causing it to slide down the ramp and into the water.
