Not certain, but “Detached” probably means unconnected to a charging source. As the numbers of such cars increase, parked in crowded public garages say at airports and hospitals, and similar “accidents” are bound to occur. Guns don’t generally go off spontaneously but people still try to sue the manufacturers. All the companies producing and pushing these cars are far more logical targets for some juicy lawsuits.
Wonder what is going to happen when one of these goes off in a basement of a high rise.
in the video others have posted in this thread the battery is sitting on the ground in front of the front wheels of the car. Not sure what was going on (theft?) but I don’t think it was installed in the car.
