Ken,
If the horn is continuously blowing in triplets, it is likely to prevent
even intentional CO poisoning.
There is no need to disable the car and risk traffic dangers. Time is
not crucial, just blowing the horn is enough and may notify people at a
distance like in a house.
The numbers could use some fine tuning but close enough to make a point.
For example the average CO deaths (439) are from 1999-2004 (Public
Health Rep. <https://www.ncbi.nlm.nih.gov/pubmed/22942466#> 2012
Sep-Oct;127(5):486-96) and percentage from automobiles 21-69% (Public
Health Rep. <https://www.ncbi.nlm.nih.gov/pubmed/21387954#> 2011
Mar-Apr;126(2):240-50). Maybe vehicle count should include trucks. I
suspect manufacturers could make a dashboard mod for under $1.
This really is introducing three questions:
Should vehicles (or heating systems) have built in CO detectors?
At what value/death should we introduce safety measures?
Do we require such measures by law?

Hi Bob- do you know what percentage of the 300 are accidental vs
intentional?
Maybe instead of just alerting, the car should shut down upon reaching
some measured CO limit.

In the US we sell about 15 million cars/yr and have about 300
deaths/yr from automotive carbon monoxide. Since DC power is
available, the horn is available, packaging is not needed,
installation can be integrated in the auto manufacturing, I
estimate an auto CO detector would cost below $10/car, about what
a household one does.
It would cost $500,000/death to install CO detectors in cars. Is
this a reasonable expenditure to mandate?
