Do you drive a car and did such a situation happen to you, in situations I describe?

It did happen to me in dense traffic, there are few ways to mitigate it but stopping in multilane road for anything but a serious medical condition or car dying would be about weighting which risk is greater, this is not about annoying somebody but safety. If I had 0 visibility through windshield and nothing else helped, in lower speed I would pop my head out a bit for example (which would clear the windshield too).

But maybe you don't drive around many french drivers :) They run very aggressively with minimal gaps, and our roads (and parking spaces) are much narrower than US ones for example. You have to drive at the limit, whole crowd always does.
