Unlike earlier air and hydro-pneumatic suspensions (think Citroen), there is no direct cross linage between the bladders or reservoirs at each corner, they all act independently via a central compressor. I think this is a design compromise that was likely made when developing Airmatic for cars, but now that the same system has wound up on SUVs, as Bacon rightly points out, you will feel the effect more the higher the centre of gravity is from the wheel hub centre lines, and the greater the difference between the road height of the wheels.

When I try to enter the local Home Depot underground parking garage, I know to have all my passengers brace themselves, as I know this particular spot can cause the effect to the degree that people have hit their heads on the door glass or b-pillar in the past.

That being said, I would not consider that a "rough ride", just an unforunate dynamic characteristic. I can see how if you had to drive over ramps and curbs like that all day, it would be too much!
