A lot of CO is generally the result of incomplete combustion, e.g. black soot coming off a candle is an indicator it's producing more CO gas. As far as the cars it's all variable, newer model cars have better combustion performance and don't produce as much CO. While on the topic the other reason it's so deadly is because it has a specific gravity of .96 so it easily travels along natural or forced air currents in a house. CO2 on the other hand is 1.5 and sinks, deaths from CO2 are rare and usually industrial such as a guy working in a tank without realizing there is high concentration of CO2 in the bottom.
You can't work in a high concentration of CO2 and not know it. Your breathing reflex is triggered by CO2 levels. Regardless of O2 level a high CO2 level will cause extreme distress.

Tell that to the tens of thousands of people that have died from it. You can be overcome quickly, by the time you realize what is happening it may be too late to extricate yourself form the area. It's common problem in coal mines becsue the walls of the mine off gas CO2. The miners call it "blackdamp". You can even have it in a sewer or basically any enclosed space where CO2 is produced.
Blackdamp is encountered in enclosed environments such as mines, sewers, wells, tunnels and ships' holds. It occurs with particular frequency in abandoned or poorly ventilated coal mines. Coal, once exposed to the air of a mine, naturally begins absorbing oxygen and exuding carbon dioxide and water vapor. The amount of blackdamp exuded by a mine varies based on a number of factors, including the time of year (coal releases more carbon dioxide in the summer months), the amount of exposed coal, and the type of coal, although all mines with exposed coal produce gas.
Hazards
Blackdamp is considered a particularly pernicious type of damp (especially in a historical context), due to its omnipresence where exposed coal is found, and slow onset of symptoms. It produces no obvious odor (unlike stinkdamp), is constantly being reintroduced to the air (instead of being released in pockets from actively mined sections), and does not require combustion in order to be released (unlike whitedamp or afterdamp). Many of the initial symptoms of oxygen deprivation (dizziness, light-headedness, drowsiness and poor coordination) are relatively innocuous and can easily be mistaken for simple fatigue, given the physically strenuous job of coal mining. The time between the onset of initial symptoms and the start of frank asphyxiation (and rapid unconsciousness) can be as short as seconds. Thus, if the warning signs are missed, a large number of miners can be rapidly incapacitated in the same short period of time, leaving no one to summon help.
In addition to the danger inside the mine, blackdamp can be "exhaled" in large quantities from mines (especially long-abandoned coal mines with few outlets for escaping gas) during sudden changes in atmospheric pressure, potentially causing asphyxiation on the surface.[1]
Blackdamp (also known as stythe or choke damp) is an asphyxiant, reducing the available oxygen content of air to a level incapable of sustaining human or animal life.
Why misquote Wikipedia or lift a quote out of context? Black damp is a lack of Oxygen

Moving the goal posts? I thought the argument was "You can't work in a high concentration of CO2 and not know it."

Because Einstein the reason for the lack of oxygen is because it has been replaced by CO2 gassing off the mine wall. CO2 is heavier than air and sinks hence the reason mines, tanks (or large containers) or even the sewer systems is susceptible to have CO2 trapped. You know that big giant yellow hose you see going into the sewer when they are doing work?
I just want to know if this Sen also wants to outlaw jogging and walking, since both produce CO2. Amazing - must be all that moist air and rain in the Pacific northwet, err, west.

Because you say so? Did you even watch that video? 100's of years of mining experience says your wrong, you can be overcome in literally seconds and if the concentration is high enough when I set that extinguisher off in the closet I may not make it out of the closet.... That's the point you seem to be missing, there is lot of people that died from this and that's the bottom line. By the time you realize what is happening it's too late.
In January, 2005 at a Sanford, Florida McDonald’s two
employees died from exposure to carbon dioxide CO2 that
was being delivered from a tank truck to a stationary
storage tank on premises. Sufficient CO2 was released to
cause both employees to lose consciousness and the ability
to escape from the confined area. As with carbon
monoxide, there is no warning and rescue must be made by
a person with an oxygen supply mask
In Cincinnati, Ohio a delivery driver succumbed to carbon
dioxide asphyxiation while dispensing CO from his
tractor trailer. Restaurant employees started to look for
the driver and found him unconscious and lying face up
at the bottom of the stairwell; they immediately called
911.
How CO2 affects the human body
• The bottom line is that if you wait until the oxygen
deficiency alarm is activated, and the deficiency is due to
the presence of CO2, you will have substantially exceeded
the toxic exposure limit long before leaving the affected
area

Since when does riding a bicycle save anything? I visited SF and they have this moronic thing called critical mass. The history of it doesn't matter, what matters now is that on the days they have critical mass, bicyclists block and tie up traffic in that city for hours. Cars can't move and people can't even cross the street.
You, my friend, have totally missed the point of Critical Mass.
now that "Nextgen" has been implemented by the FAA we have more than double the amount of airplanes flying at these insane low altitudes, crop dusting everyone with jet fuel all day long.
Airplane fly here in Brooklyn at 30 second intervals.....2 planes per minute, 120 planes per hour, and 1200 planes per a ten hour span, emitting toxic jet fuel all over the United States....everyday, all day long.
and besides the toxic fumes it is also noise pollution
Doesn't this concern anyone, I know it concerns me.....
