Cybertruck exoskeleton provides EM shielding due to its stainless steel material, that becomes magnetic when cold worked. The fact the stainless steel is not painted allows for greater EM energy absorbtion. Lastly, the angular planar shape reflects EM energy like a stealth fighter.
Honeycomb structrual shapes absorbs EM energy so the use of Honeycomb structure by Tesla protects, at least to a degree, the batteries from EM energy. Thus reducing dendrite growth and spontaneous combustion.

Elon Musk: Tesla is going to change alloy of the Cybertruck electric pickup to 30X steel not 304.
There is no evidence to show Tesla is concerned or has ever had any issues related with EM waves or that Cybertruck was designed to be EM shielded has no other car is being developed with this technology.
The Tesla honey comb structural battery design was made to protect the driver in case of high speed car accidents. Also to prevent the batteries from flying out the car and causing hurt or damage to others. There is no evidence to show it was because of EM wave concerns with Tesla.
Tesla cars doesn't have any issues of spontaneous combustion or having any issues with batteries forming dendrite. There is no reported evidence of this either.
These hypothesis being propagated are all " CONSPIRACY THEORIES " to try and tarnish the image of Tesla and Elon Musk.
After all if any of these fabricated stories, assumptions and guesses were remotely true against Tesla , the author of such hyperbole would be. filing cases with the NTSB / NHTSA. The fact that no cases are being filed is evidence that none of this is true but all fabricated lies.
