Completely fair. What I see in bad conditions is that traffic starts from a condition where each vehicle has sufficient stopping distance despite ice/snow, but then something changes, like a vehicle entering that lane without a wide enough opening. That causes a cascade of slowing, which compresses the “accordion” of following distances. If the car that initiated the condition then comes to a sudden stop, vehicles several cars back have insufficient room to stop, since there was not enough opportunity for each vehicle to recover to a safe following distance.
