Camaro is 100% at fault....he came up too suddenly then try to crowd between two cars....I don't blame the pickup for being pissed..
Not blaming him for being pissed is one thing but not blaming him for the behavior that followed is quite different.
Camaro was 100% at fault for flying up the right lane and trying to cut off the PU. Once that incident was over, instead of just letting it go the PU driver was out to teach a lesson.
From a legal standpoint they both committed infractions that led to the accident and I bet both their insurance companies are studying that video to see if they can deny the claims for reckless driving. Especially when the Big Rig’s insurance company comes a callin’.
