It is plainly obvious that CO and even CO2 from IC engines is drastically more fatal than anything coming out of an electric motor...I thought the trolling attempt was transparent, but apparently not. If I really wanted to provide a counter to the article, pollution from battery manufacturing is far more concerning than ozone (which has a half life measured in days) from brushed electric motors. And even that appears to be far less of a problem than the carbon economy.

That being said, ozone can be fatal over the long term, and researchers regularly segment pollution death estimates to include ozone pollution [1].
