For example, look at the distance sensors used for parking and the data coming from them over the CAN bus.&lt;p&gt;That bus needs to be able to (at least indirectly) reach the brakes so that automatic emergency braking can take their measurements as inputs. And that bus needs to be able to reach the audio system to provide audible feedback to the driver when parking, and also mute the radio. Ergo, you have a bus that reaches both brakes and radio. Now, you might want to prevent the radio firmware from sending data to the brakes over that bus, but physically you have to have a connection between them, as we don&amp;#x27;t really want to make many separate buses for reasons of complexity, cost and maintenance; moving from a separate end-to-end wire for each specific purpose towards a shared bus was a great improvement.</text><parent_chain><item><author>Loughla</author><text>Exactly.
