Why is the inhalation of automobile exhaust fumes life threatening?

Inhalation of automobile exhaust fumes is life-threatening primarily due to the presence of toxic components such as carbon monoxide, nitrogen oxides, and particulate matter. Carbon monoxide can interfere with oxygen transport in the blood, leading to asphyxiation. Additionally, the particulate matter can penetrate deep into the lungs, causing respiratory issues and increasing the risk of cardiovascular diseases. Prolonged exposure can also lead to long-term health problems, including cancer.
