Car exhuast healthy or unhealthy for plants?

I was just searching on different ways to produce CO2 and found a little research on the exhuast from a car having CO2 levels almost the same as our exhalation. Any one got any ideas?

VERY UNHEALTHY!... Surely you know that?!...

dont cars produce carbon monoxide? thatll kill you.

As your cars exhaust does contain carbon dioxide, it also contains carbon monoxide which is deadly to plants as well as humans.

I'm just a retard and think about all the wrong things, and skip over the important stuff. But I haven't even tried this yet so thats good! Thanks for all the replies guys!

well glad you didn't, since most isn't CO2 but COx, so monoxide which is quiet lethal

well if your car ran on natural gas then yes it would work, i have seen/ran the exhaust from ng powered generators to the grow room as a source of co2, with frequent air changes mind you, i have also used the vent from a hot water heater as co2, just think how a co2 generator works then you will see all kinds of possibilities
