Interesting observations, I've seen it and thought along similar lines myself.

I suppose a fully submersible submarine is close to being in a continuous fluid, with air acting like a fluid as well.

The whole ground plane thing (pressure wave) really makes cars/truck unique, aircraft only experience this during take off and landing.
