This morning the DD was covered by mist and dew. Being in a hurry I didn't wipe off the side windows and instead ran the front windows down so I could see left and right as I left the development.
When I ran the windows closed I experienced a miracle -- the front 12 inches or so of each window was clear of mist and water, allowing me perfect visibility of the side mirrors.
I thought to myself, "Boy, what a clever design feature -- self-cleaning side windows. And it is a safety feature, too!"
A couple of minutes later I'm thinking, "Nah, Dodge ain't THAT clever."
And even later I'm thinking, "Doofus, you're JUST NOW noticing this?"
So what do you think: design, coincidence or doofus? Your vote counts. :-)

 

Every car I've ever owned does this.

 

I haven't noticed a vehicle yet that 'cleared' only the front part of the window when it was rolled down. I'll have to check mine. lots of rain here today at the beach.

 

It's the weather stripping, it naturally clears the snow and fog off when you roll them down.

If you live in a really cold climate, like up here in northern MN, the windows will usually fog right back up, until the vehicle is warm enough.
