I had two occasions like that: one was in Spain, where I had to look down through my opened driver's door to look down to follow the center line. While creeping along, it didn't occur to me that someone elsecoming from the opposite directioncould have the same idea!
The other was recently in Florida, needing to cross a 4-lane highway. I rolled both windows down and listened for traffic before crossing. :-/
Wow, I don't think I would have been brave enough to cross that four-lane highway.
What I always loved when I lived in snow country was not being able to see past the inside of the windshield. when that happened I would drive looking out the passenger side window to guage how close I was to the guarde rail to make sure I kept driving straight.
Really glad I no longer have to drive all those miles for a living.
