I'm guessing you didn't drive an early ford with the windows experience. my favorite was driving a rental car where a popup popped up over my speedometer while driving. there was no "touch", so I couldn't press the "OK" button, and there were no buttons on the steering wheel I could ever find to press it either (there were in later model ford cars).

I ended up having to power the car off to get the dialog to go away, but in the meantime, drove in the right lane because I had no idea if I was speeding or not, and couldn't imagine trying to explain that to a cop if I were pulled over.
