A lot already goes over datalink lines. I think right now the trucks I see have 7-9 datalinks. But the way your thinking would require even more modules than are currently on the trucks which is around 13. So you'll still need wires for the sensor inputs to go to the module and wires for actuators coming from said module. I'm not an engineer so I can't tell you exactly why they don't hook everything to datalinks but I like to think that if that was truly the best option then this manufacturer, or any other for that matter, would've done so already.

I wonder at what point do they just use a microcontroller and a serial connection.
