UPDATE:
Oh dear...noticing the vehicle description on top is a shocker... I was chasing a Toyota Camry that ran 2 stop signs, not a Jeep Grand Cherokee. Yet, that plate I saw is what was on the Camry. So whoever drives the Jeep, I apologize. I was mad at a Toyota.
It's clear, no cars in front of him, why does he need to stop to make just...one...lane...change? He could have done it further up. So why?
