> The slowness is the result of people trying to merge into the highway, not "bad drivers". I stand by my point on "bad drivers". It's a well-studied phenomenon[0] and it's not a matter of opinion. [0]: https://www.youtube.com/watch?v=t4m-OJosGaI
That is a mathematical model explaining one type of traffic jam - the "phantom" traffic jam. It can explain a traffic jam on a straight section of highway with no entrances or exits -- but imagine what would happen to that model if a second line of traffic with the same density of cars tried to merge in! According to a 2005 report for the Federal Highway Administration, the leading cause of congestion is bottlenecked…
If the drivers staying in the far right lane didn't do that mindlessly (their exit is not next or soon, why are they there?) or if they actually kept space open ahead of them for the cars they can see are about to merge, these problems would largely evaporate.
I'm paraphrasing poorly but, "do things slowly so that they go smoothly. Things done smoothly go fast."
