I'm not sure how. My understanding is these adjust to driving conditions which include driver input (steering, throttle, etc) they're also electronically controlled. So they not only need signaling to determine driving conditions, they need power too. Anything self contained would essentially be a passive system, which is what we have now, or what Chevy is using in the ZR2
The only other way to get something similar was if they had batteries and communicated with each other wirelessly to know what the other is doing. That doesn't sound reliable or cost effective and still wouldn't have the benefit of knowing what the steering wheel, throttle or brakes are doing.
My guess is the new shocks will make on-road behavior quite a it better, particularly in the rear. Time will tell
It wouldn't be hard to profile different driving conditions with a simple onboard accelerometer and travel meter
Smooth, small, high frequency vibrations = Highway.
Large, fast shock movement = high speed off-road.
Hard compression followed by full extension = jump.
Frequent accelerations, decelerations, and lateral changes = spirited driving.
Lateral G's = cornering.
Negative G's = Braking.
Slow, large shock moments and lots of body roll = rock crawling
Every road and driving situation has vastly different accelerations and travel movements, making it easy to accurately adjust the suspension without communicating with the truck or driver.
That said, knowing the the mode the truck is in will allow it to preset the dampening instead of reacting to it a fraction of a second after the driving conditions change.
But as others said, keeping a battery charged would be a PIA and if you are running power, you might as well run a signal too.
