I wonder if that little feature was added to help win over Chinese buyers?

Elon Musk Says Tesla Cars Will Reach 620 Miles On A Single Charge “Within A Year Or Two,” Be Fully Autonomous In “Three Years”.

Actually, that's an exaggeration:

Quoted from some talking head:

HEPA filters are fine enough to stop most bacteria, like anthrax and the plague, as well as dust and pollen. But viruses are smaller than bacteria, and could likely get through the filters. Gizmodo talked with Michael J. Buchmeier, deputy director of the Pacific Southwest Regional Center for Biodefense and Emerging Diseases at the University of California, Irvine, and he allowed that smallpox and influenza could get through the HEPA filters.

So while your air will be safer in the Model X with the bioweapon defense mode deployed, it's not a 100% guarantee. And, more importantly, you'd have to know there was a biological attack happening, when in reality those aren't usually detected until it's too late. In the end, bioweapon defense mode will get you some nice clean air, but it's probably not going to save you if there's a real bioweapon attack.

Yeah, nothing's going to save you if there's a real Bioweapon attack. 

But it's interesting that Tesla thought to market that. 

great marketing. #zombielove

To your point, zombies are big right now so this was quite clever marketing. :)

Given that the Model X is two years late, I think Musk is a little over optimistic in his predictions. It'll be interesting to see what Apple comes up with car-wise. They certainly have a lot of cash to throw at it.

Apple does have a lot of cash, but I thought they were struggling with the Apple Watch?

Apple Car would me a much bigger investment than Apple Watch.

So perhaps Apple needs to focus on Apple Watch for now.

And yes, Elon has always been an optimist when it came to timeframes, it seems.

For example:
