New Harvard Study - Stricter Air Quality Needed to Prevent Deaths

So true.

It's the combustion of the engine taking the oxygen.

I wonder at what level the car engine would stop working first? I would think it would die before a person does, but they would probably be rendered unconscious.

I'm not arguing with your comments. However, if the CO doesn't get you, the CO2 will. Both are present, depending on humidity, through the reaction, CO + H2O = CO2 + H2. Introduction of CO2 into a confined space can be deadly. It is heavier than air, and it's colorlous and odorlous. Victims pass out, and die of aphyxiation rather quickly.

NIOSH report details dangers of carbon dioxide in confined spaces

The potential health effects of exposure to CO2 levels between 2 and 10 percent, according to Benaise, include: headache; increased heart rate; dizziness; fatigue; rapid breathing; and visual and hearing dysfunctions. Exposure to even higher levels can lead to unconsciousness or death within minutes of exposure.

People have been using running engines to commit suicide since there have been automobiles. It's not oxygen depletion that kills you, it's carbon monoxide, or CO.

CO is not present in the exhaust of a properly working computerized vehicle for a long time now.

While CO emissions in modern engines is relatively low, it is far from nonexistent.
