Who is to blame for this tense car accident?

This footage captures a near collision between a red Dodge truck, causing the driver of the speeding black Scion to overreact and over-correct his vehicle which led him to drive across the median of US17 and collide with a black Ford Expedition. The red truck fled the scene at a very high speed. The police have no interest in seeking the driver of the red Dodge Ram truck for his actions leading to the collision. The driver of the black Scion was ticketed. Only minor injuries. So... who is to blame?
