   (1) Car exhaust consists of several gasses, including carbon dioxide and carbon monoxide, as well as water vapour, all of which are invisible at summer temperatures. When the temperature drops, the water vapour condenses and becomes visible.
   (2) Your own breath also contains carbon dioxide and water vapour, and similarly, the water vapour is what you are seeing in cold weather.
   Even if you inhale car exhaust in cold weather, the visible part of what you exhale is nothing more than water vapour, much of which comes from your own lungs. The amount of car exhaust that you inhale in open space is very minute.( In a closed garage, it may be enough to kill you! )

   Could be the chemicals you breathed in. I know people in NY can see the exhaust every winter on cars some white others black its how much oil is being burned and how much pollutants are in the exhaust. Which is why I hold my breath during the colder season when walking past the back of a car. People in California dont notice this as much cause the warm are helps spread the vapors around so you dont get hit with them as much in the cold air the vapors stay together and are more concentrated when ya breath them in. Another thing to notice which if you are a smoker will be hard but during the summer I can only tell a smoker when they recently had a cig. but its not that bad. People who smoke during the winter give off a more offensive and stronger order of concentrated smoke cause the air is cold and the smoke does not to say float away as well as the summer so it collects on the warm smokers and is stronger.

   “Why is it that when you breath in gases from cars or anything that releases gas your breath seems to come out way thicker and in a darker shade of grey?”

   That’s because if you inhale something dirty…you will breath out something dirty.
   Of course some of the filth stays in your lungs….that’s what we call air pollution.
