You don’t seem to know that carbon monoxide and the like is TOXIC and CO2 is not in lower quantities.. That’s why we have cats,
In addition ICE engines emit particulates that clog lungs and exacerbate lung disease…..cats save lives by reducing lung diseases . CO2 is a more existential threat. Cats are not cure alls regardless….they maybe about 75% for some toxic shit but they still can’t completely clean up emissions. ICE engines are ugly shit producers when operating, EVs are NOT. THEY PRODUCE fewer to no toxins when operating depending upon the battery used, tires,plastics etc. Geesus, plastics alone used in all cars emit greenhouse gases when exposed to the elements…in addition to being toxic.
