Where in the world did anybody ever get the idea that exhaust gasses are heavier than air? Every 4th grade science student knows that hot air rises and exhaust gases are considerably hotter than ambient air.

If exhaust gasses were heavier than air how would a hot air balloon ever get off the ground. After all, they operate on hot exhaust gasses.

Carbon Monoxide is only slightly lighter than air (97 percent) so you can't always count on it rising. It mixes fast and cools with air fast, so it can be in your face before it ever had time to rise.

It's also somewhere between 700 and 1300 degrees hotter than ambient air and rises rather rapidly as a result.

Sure, at the point it leaves the exhaust pipe, but how quickly does it cool. You can stand in front of the tailpipe without getting burned. By the time the CO is a few feet away it has already cooled enough to collect wherever it wants.
