Chaos and "control"

Traffic jams despite AI & Co.: what really slows us down

Driving slowly is sometimes the fastest way to reach your destination. But even AI and intelligent traffic systems are powerless against unteachable drivers.

You're driving briskly along the highway, the traffic is flowing. Suddenly the display board shows a 60, even though the road seems clear. This begs the question: "Why slow down now?" These speed limits are not arbitrary, but part of a sophisticated algorithm to avoid traffic jams.
