Carbon dioxide (CO2) trapped in low-lying areas can be lethal to people and animals. Carbon dioxide constitutes approximately 0.04% of the air in the Earth's atmosphere. In an average year, volcanoes release between about 180 and 440 million tonnes of carbon dioxide. When this colorless, odorless gas is emitted from volcanoes, it typically becomes diluted to low concentrations very quickly and is not life threatening.
To my knowledge, not much SO2 is produced by cars, but huge amounts are generated from other anthropogenic sources like coal power plants. In summary, volcanoes do emit gases that can have adverse affects on our climate, ecosystems, and health, but the scale is much smaller than that produced by humans.
