I was paying extra attention to the Silverado since I couldn't see through him. Next time I'm going to leave double the gap.
I am pretty sure what happened is he wasn't paying attention then saw the Prius at the last second. Everyone behind me assumed everything was fine since he was going at a good pace.
It did sound really cool. Heard my tires and then the big crash sound from impact. My hearing was extra sensitive because I was trying to listen to see which side of the car I was going to rip off... left or right.
