NIO is applying for a patent for a "vehicle self-destruction system" from the U.S. Patent Office. In short, when the vehicle detects that the situation has changed and is beyond human control, it will immediately remind passengers to get off the vehicle and the vehicle will go to the "self-destruction" site on its own. Since this summer, there have been many spontaneous combustion incidents in Weilai vehicles. This patent can minimize the harm to surrounding people.
