So, maybe fit a side scoop along the side to vent the footwell? Or drive in the rain to keep the dust down?
The rain was what clued me in. I got caught out in a light shower and when it was over, I pulled off and toweled the screen dry. The front was pretty clear as the water had been blown off. The inside was really covered! This all came from the front following the transmission tunnel then into the car. Those gaps are huge!
It made the regular grime turn into an interesting mud...
