Exactly, and that same theory also applies to long slow breaking as well.
What you are refering to is the well known phenomenon of traffic waves or phantom jams. The UK has all but eliminated them with variable speed limits without the need to make every leave half a mile gap between each car.
We have variable speed limits on parts of our roads. People commonly exceed the stated limit by 20+ mph since they're used to "full speed" and ignore the instances where it's being reduced.
I welcome our future robot car overlords where all of these problems should in theory be greatly reduced or eliminated entirely.
Where I live it is impossible to exceed the variable speed limit because every other car on the road is doing it.
I agree, a full network of self driving cars which can all move together in a chain will eliminate this problem. I just hope I live long enough to see it.
