Mind Blown · Selfish routing: Braess's paradox

The shortcut that slows everyone

The new road is free, instant, and takes nothing away. Why is everybody's drive fifteen minutes longer?

Four junctions, two narrow streets that jam and two motorways that never do, and a free hop joining them in the middle. The tabs open and close that hop, and the slider sets how many drivers are out. Watch what each driver pays go up the moment the free road opens.

Board: The Road That Slows Everyone →

Three panels stack on a narrow screen; the slider and the tabs stay above them.

try this Switch between No shortcut and Shortcut open and watch the minutes under What each driver pays.
