Yup, CANBUS has been a heck of a copper saver. All sensor signals running on a single circuit/wire.
I have not messed with canbus much, I soldered a db9 connector onto one of my cars so I could do fun computer hacking, turned out the easiest place to do that was the rear tail light.
but personally I prefer wires and mechanical connections.
I want a steering rack connected to my steering wheel,
a master cylinder connected to my brake pedal and clutch pedal, A car that has a cable that runs from the throttle pedal to a throttle body. I don’t need a computer to wonder what I really want.
