From the Google translated version of the article it looks like it's only dangerous when burned.
To be fair, most things are dangerous when burned.

I guess there is a point that the dust will always be around the car. But while driving it does not look like the driver would be affected by it: http://www.ozeninc.com/images/hpc-carmesh-2.jpg
They're racing against other cars, cars to the right, cars to the left, cars in front. I don't see what the aerodynamic profile is meant to inform us?

#53Carbon fiber once burned at high temperature breaks down sufficiently for it to penetrate mucous membranes. The risk highlighted by the Germans here relates to the ash left over after the fire. i.e. Hinting a potential long term dangers / contamination from the ash floating around.

That's not what the OP was talking about however. The fact that carbon fibers are not present in nature only tells us that we didn't have to evolve anything protecting us from it if it's really dangerous (since it was never a selection criteria). That doesn't mean it's necessarily harmful though.
Disagree; OP was talking about why no animal in nature produces carbon fibre, given its dangerous to others nearby. Was it ecological pressure? I answered, yes that's possible.

#56I find it interesting that this article was yanked from Hacker News just as quickly as I saw it. I clicked on the link, wanted to go to the discussion and had to find it through search in spite of its high vote count and recent submission.

Washing air-breathing lungs with water sounds problematic, although with fluro-carbons and the prevalence of lung cancer I am not going to say no-one hasn't tried !
You could wash one lung at a time. Or use extracorporeal membrane oxygenation. Water in an of itself won't hurt lungs as long as the patient gets enough oxygen.
Yes it does: http://en.wikipedia.org/wiki/Drowning#Secondary_drowning
If you ever get saved from near drowning, you are still not safe.
