Annoying?
Don't you want to be able to see where you're going?
What would you do without it?
Have someone sit next to you and give your monitor a wipe with a paper towel when you pitted?
Hmmm. That's an idea for more realism. I suppose that they could also splatter dirt, oil, and squashed bugs on your monitor while you're driving.
What are the chances that we could talk our wives and lady friends into doing that?
