"gasoline engines cause is CO2, which is completely non-toxic to humans."

I believe you're thinking of CO (but it's still toxic). Hemoglobin will uptake CO more readily than O2, and will kill you quite rapidly. Although C02 is definitely a byproduct, the CO will kill you before you experience CO2 poisoning.

CO2 is most definitely toxic. Why do you think our bodies expirate it? OSHA considers anything above 6% concentration in the local beathable environment deadly (because it lowers the O2 concentration below 19.5%).
