Foggy windows
"The reason for foggy windows has to do with temperature and the air’s moisture content. On a cold day, any moisture in the air inside your car — from passengers exhaling, from snow on your boots, etc. — turns to condensation when it hits air next to the window when the temp outside is colder."
Something to do with dewpoint. These remedies are on their website.
"For a quick fix: Lower the temperature inside your car rapidly by turning on the defrost vent with cool air or cracking a window; don’t turn on the heat. This will make the inside of your car cooler and help reduce the fog. Also, turn on your car’s rear-window defogger to help clear up the back window. Though this is a fast and effective method, it could leave you shivering."
Here is an old Okie trick I learned from the farm owner where I worked in high school. It surprisingly works, if you can bring yourself to using it on a Corvette.
1. Use a clean potato, one that has had the soil washed off. A potato that is growing eyes is okay.
2. Cut it in half.
3. Rub the open part of the 'tater on your windshield.
4. This not only cleans the windshield but it prevents the build up of moisture on the glass.
If you can't do the potato trick, buy one of the many products available that help stop the build up.
I fly through ORD several times a year, Next time you fly over YVR wave! You'll see my car parked 3 miles due south of runway 26L in my driveway.

Cool!
I retired from Boeing last year, so I don't get that way anymore. May start up as a contract pilot in May.
Thanks,
