Microscopic Shockwave Physics (IDM)

When a vehicle stops suddenly (e.g. for an illegal drop-off), reaction time lag causes trailing drivers to brake harder than necessary. This over-braking amplifies backwards as a backward-propagating shockwave (-18.4 km/h), causing phantom jams and intersection blockages long after the hazard clears.
