Just thinking, while the early prognosis on wet weather visibility is positive, Pags admits it would have been good to do more running and together.
The back of my car gets plastered in mucky spray from the road, could a similar negative pressure delta in the cockpit cause finer spray to get sucked in and onto the back face of the screen? The driver would have no way of clearing it manually, it's out of reach. Just a thought.
Does Indy race in the wet ? I don't follow the series much, but I can't remember seeing a wet race.
