Thanks. I bet like most things in this world, this design grew organicly. It seems like a good design in a very noisy environment and it does allow the car manufacturer to easily add in new controls ( volume up for example ) in different locations that do the same thing.

And thank you for the polite response, I appreciate it. One further nice thing about CAN, because of how it works electrically (basically logically zero always wins) it is trivial to have messages (and message types, I only described the most common data type) of different priorities. So a low numbered ID always wins. That also allows a trivial DOS, oa bit blaster that repeats something like 000000100001...CRC... might not even trigger an error detection. It really is quite a nifty thing, amazing it works so well too.
