Why is -5 mph more hazardous than +5 mph?
A slow probe vehicle forces multiple approaching rear vehicles to execute rapid braking or dynamic MOBIL lane changes into adjacent traffic lanes. This creates cascading shockwaves, high closing-speed conflicts, and blind rear-end vectors. Conversely, a vehicle traveling +5 mph approaches traffic from behind with clear forward sight lines, managing active overtakes with minimal disruption to trailing flow.

Observed Proof: Slow Probe (-5 mph) generates 2.33x more brake shockwaves & conflict vectors than Fast Probe (+5 mph).
