Why couldn't they have just left it as "it's a really good air filter"?
If you're in the vicinity of bioweapon aerosol, the particles will possibly still be present in air once you get out or will have coated your car. Also, for some of these organisms, you only need to inhale < 10 cells for it to cause disease [1], so the filter needs to be (literally?) 100%.
So, unless Tesla plans on packing powered air purifying respirators [2] in their cars, this is a gimmick.
I think people read it too literally right now. If you say some road bollard is so strong it could survive a bomb explosion you usually don't expect bomb explosions. It's just that it survives large forces.
This system stops particles as small as ones that could be used in bio weapons. It's a theoretic comparison, not a warfare ad.
Yes, I did read it. That's how people talk about products these days (unfortunately). But we didn't talk about it that much in case of tank-proof audi:
You're not expected to test either one of those claims. They're just there for comparison of what the product is theoretically capable of. (or going the other way, one could complain that anything below 200mph is not ludicrous)
That doesn't seem like just marketing for the Audi. It seems like the car is seriously intended for individuals who may be attacked, politicians, very rich/powerful people in unsafe areas. It's not for your grandparents to drive to church on Sundays. It looks like most people buying it are politicians and diplomats. The security features are also an upgrade that costs like $600k.
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.
It's class BR7 protection. That means it protects from lead bullets. That's all. Here's a list of examples of what it doesn't protect from: AK47 with hardened or armor-piercing bullets, incendiary bullets, tank fired shells.
There is a subtle but - military cannot use bioweapons due to Geneva. Only in Syria they can, but the market for Teslas there is limited. You cannot charge it, there are barely any roads left to drive it on and you will be dealing with a lot of legal to use military stuff raining on your head that Tesla has no protection from.
So that is a statement that cannot be put to the test.
I'll be incredibly pedantic here - isn't it the same as saying that a car can technically go 180mph? The only place on earth where you can drive that fast legally is the German Autobahn, so for 99% of buyers it's absolutely irrelevant. So is defense against bioweapons - what this tells me, is that the car has REALLY good air filtration system, just like the fact that the max speed is 180mph tells me the car is likely very fast. I don't need to use it in a bioweapon contaminated area, or take it to 180mph to find either of those properties useful. They are both useful even when not taken to their absolute limit.
By that logic, you can test your tesla's bioweapon defense system by putting it inside a controlled environment where the system will be put to the test - just like the car is tested to its limits in a controlled environment - ie racing track. Doesn't change the fact that we are still taking less than 1% of the customers here.
Countries have managed to avoid chemical or biological attacks against each other since WW2 (Vietnam and Iraq-Iran being notable exceptions AFAIK). Laws of war are generally taken more seriously than the speed limit.
That's the sort of thing you say when your bollard is not strong enough to stop a fully-loaded tractor-trailer driving into it, which is the use case you would expect for a bollard. Mentioning bomb resistance is just trying to equate different types of large forces in the mind of the buyer.
If a bomb goes off, no one would even care whether that one stupid bollard survived it. The major failure mode of a bollard will be due to buckling, shearing force at ground level, or cracking the foundation cylinder, as the force from impact is transmitted down the lever of the bollard into unyielding earth. And even if the bollard itself is destroyed, it is still partially successful if it can slow down or stop the truck. Does hiding behind a bollard protect you from a bomb? No. Bombs and bollards just don't ever meet in real life.
Bioweapon defense mode is something I would expect in a top-shelf building HVAC controller for hospitals or AAA office space. The bioweapon defense mode that already exists in my own car is "drive as fast as is prudent, away from the attack site, without stopping to refuel/recharge". The bioweapon defense mode for my own home is putting duct tape on the edges of the windows and doors. Anything more would be overkill--a waste of money, over something that will likely never happen.
What is the actual use case here? Pollen. If you're allergic to tree pollen, you will sneeze less on your way to work while driving the Tesla in the spring. Is that statement not exciting enough to sell those cars?
