yes but actually no. There's a hidden pull cord under the bottom mat of the "map pocket" that you have to remove, along with whatever else you were storing in there at the time. That's assuming the cord hasn't fallen out of reach inside the door or otherwise become inaccessible during an accident, of course.

The owner's manual section on "how to open the door if there's no power" spans 4 pages (viewed on mobile) and has 3 diagrams to illustrate the steps.

(incidentally, opening the frunk with no power is a separate page with ten steps and begins, "To open the powered frunk when Cybertruck has no power, you need a power source that provides between 9V and 16.5V"... it's like they're trying to be shit.)

Pretty much all Chinese EVs use LFP batteries. You can hammer a nail into one and it'll just stare at you like you're some kind of dumbass.

Western made ones use NCA or NCM batteries because of range anxiety. But those ones are armored AF so good luck doing any significant damage to them. And I suspect they'll also switch to LFP within the next decade or so anyway.
