In racing simulators, I like the internal views, but for a better use of the visible area, I prefer to play in the hood view. However... I greatly enjoy the dirty and/or wet windshield effects, which only occur in internal views.
I always imagined a "virtual representative version of windshield wiper" would be a generic effect for those who play in the hood view and even view of the car in third person, preferably would be an optional effect.

Anyway, I decided to make an image to get a better idea of what it would be like. Of course my art is badly done, but imagine it well made at 60FPS and with dirty and wet effects running down the monitor =D


In additional, the sound effects are different on inside or outside of the car. The choice of sound type could be separated from the type of view.
