Again, you are talking about CO (Carbon Monoxide) not CO2 (Carbon Dioxide) which is the gas in soda water and all carbonated drinks.
CO2 can very much kill too, if enough accumulates to displace the oxygen. This is a very real danger in silos and some mines, among other places. Some of them would even be equipped with CO2 detectors for safety.
Suicide by engine exhaust is very nearly impossible with modern cars that are running properly.
