So, it is kind of cold outside. You turn your car on and start driving and suddenly the windows start fogging up and you can't see but you're already driving.
Before you end up killing yourself here's an idea:
Roll your windows down. Yes, I am aware that it is cold out, but trust me, within seconds the fog will dissipate if you roll them down. Actually, you can avoid being blinded altogether if you just roll them down for a few seconds right after you start your car to even things out.
