How cool would it be if the Model S and X had a hyperbaric feature? I think a lot of people would buy that option (assuming the cost was reasonable). Is this something that’s possible, especially with bioweapon defense mode? I’m surprised Elon didn’t think of this yet. I would feel silly buying a dedicated hyperbaric chamber for home, but if my car had it, I would use it all the time. On a side note, does bioweapon defense mode block-out all outside air and only recirculate, or does it still bring-in fresh air? If the former, wouldn’t you eventually run out of oxygen?
