NEW YORK — Two deadly incidents on New Year’s Day — an attack being investigated as an act of terrorism in New Orleans and an explosion of a Tesla Cybertruck in Las Vegas — both involved vehicles that were rented on Turo, a peer-to-peer car sharing company. Early Wednesday, 42-year-old Army veteran Shamsud-Din Bahar Jabbar rammed a pickup truck into a crowd in New Orleans’ famed French Quarter — killing 14 people who were celebrating the New Year.
