I've read that many people kill themselves by using the exhaust of their cars in a closed garage. Does that work?

Yes, carbon monoxide from running a car in an enclosed garage can be deadly. The gas is an invisible and odorless substance and can quickly replace the oxygen in the air, causing asphyxiation. Prolonged exposure to high levels of carbon monoxide can be fatal and therefore, using the exhaust of a car in a garage is a dangerous and potentially deadly practice.
