I see many signs on stations warning people that trains as they come in there is air turbulence and people need to be aware and keep clear behind the yellow line, etc. The sim should try to visually show this happening in essence. I know it's an invisible force and you can only feel it, etc. but there has to be some way to show it visually such as may be leaves or paper flies around, light dust or a noise even.
Or you could indicate this by slight camera movement. So with all your camera suggestions, this could be a whole "camera overhaul".
