Traffic

tap one brake. ruin everyone’s day. forever.

a ring of perfect drivers — one tap births a jam-wave that never dies

No one crashes and no cause stands out — one driver taps the brakes once, and the slowdown becomes a wave that keeps moving through the ring long after that driver has sped back up. The jam is not stuck to any car; it is a pattern in the traffic itself, which is why it does not clear on its own.

Concepts: traffic-flow, emergence.
