It has a built in "patented emergency exit system, a fire extinguishing system and an emergency fresh air system" [0] and the windows on the standard model can't even be opened/closed. And get this, that emergency exit system will blow the freaking doors off the car so you can exit.
"If the doors can no longer be opened normally, an Audi-patented pyrotechnic system simply blows apart the joins between the doors and the vehicle body and you walk out without even grabbing the door latch." [1]
This Tesla is being pushed as helping people deal with air pollution, but "it can withstand a bioweapon attack! For real!". That Audi is literally for people who might drive over an IED, or get pulled over by a jeep full of people with machine guns.
