I always do this, but when I try to pull out of the drive the windows all steam up. Meaning I'm now sat in my car for 5 minutes waiting for them to clear anyway.

(I'm very much against wiping the insides of the windows as the smearing can make driving at night very dazzling)

I start my car, put on the heater and airco. Start scratching my windows clean and by the time I'm done my car has warmed up enough for the windows not to fog up. :)

Seems like the best way to go to me, but, in Germany apparently you have to start driving with foggy windows :s (ok, or buy an auxiliary heater)

What would cause this? Scraped the ice in Wisconsin for years and nothing steamed up. Only rain makes me steam up.

What if you open the driver's side window at first?
