You are most certainly technically incorrect, which is the worst kind of incorrect. It would take very very high levels of ozone to be anywhere near as promptly fatal as carbon monoxide poisoning from running a gasoline powered car inside a closed garage. As far as I know, no one commits suicide by running an electric motor in a closed room. Ozone causes oxidative damage to tissues, including the delicate tissues of your lungs. Carbon monoxide shuts down the oxygen carrying function your hemoglobin. You can be killed by unnoticeable levels of carbon monoxide. It's highly unlikely you won't be able to sense dangerous levels of ozone. In fact, it's likely to be unpleasant enough to drive you from the room. Whereas CO makes you feel sleepy as you slip down to unconsciousness forever.

(EDIT: That said, ozone in rather small amounts can be quite damaging to long term health.)

Not true. Brushless induction motors don't produce ozone, and that's the type of motor used in the Tesla, Leaf, Volt, i3, and any other electric vehicle on the road. Schwarzenegger wouldn't be dumb enough to end this letter with a claim that wasn't fact-checked.

I just found this link http://www.science20.com/news_articles/solving_ozone_problem... . I am sure this will be a problem for many years but it will be addressed. The problem on the other hand is the pollutants from automobiles. If someone is driving a car in New Delhi with windows down for few hours, can feel the grease from engine fumes on face and nostrils. Clean your nose and that is when you realize how terrible the traffic is. The problem is not with people who are driving the cars. There are pedestrians and people living off streets who breath that air all day. It scares me to see a child breath that air as I am tend to fall sick with throat ruptured even after a day on the road inside a car. That would hopefully change around the world if we have electric vehicles.
