Here is the first remIOTA animated demonstration.
A rotating highway section with three vehicles increasing and decreasing in distance between each other. As the distance closes, due to the phenomenon refereed to as platooning, the following vehicles will receive some decrease in wind resistance. And depending on multiple variables such as primary vehicle size and speed, you would see a fuel efficiency boost.
At the cost of being extremely dangerous, and actual savings are only gained over time, the practical use is lost in today's commercial and industrial logistics. However, the next generation of AI assisted or self driving vehicles would be able to utilize such a method with the push of a button, or make the decision for itself.
