You read that right, Tesla model S and X both have a BIO-WEAPON defense mode. This is not a joke and is completely real and functional. Also, I know this may be old news for some, but I thought I would share.
Bio-Weapon Defense Mode
Model S now features a Medical grade HEPA air filtration system, which removes at least 99.97% of particulate exhaust pollution and effectively all allergens, bacteria and other contaminants from cabin air. The bioweapon defense mode creates positive pressure inside the cabin to protect occupants.
