Ah, I see. Not segmented pipeline, segmented pipeline control. That makes a little more sense. However it might make it significantly more difficult to make coordination between segments possible: The self organizing behavior at work with car driving may be significantly different than what is required for a pipeline.

People driving cars are essentially doing what is best for themselves individually (within the bounds of the law), and that ends up translating to something that works for the whole. With a pipeline, that might not work: If pressure gets too high in one area, it might take highly coordinated control across thousands of miles to bleed off contents into buffer tanks & ease pressure a dozen segments away.

I'm not saying that couldn't be done, I'm sure the SCADA systems could be isolated from each other in this way, it just seems like it would require a lot more difficulty with explicit coordination between technicians, not a self-organizing system such with driving on a highway.
