Camaro 100% fault. For the dude who says speed lane. Read your Driving Manual again. It is not speed lane. If you are going within speed limit, you are not obligated to move off right or left lane.
And, if you look closely there was another car in front of Pickup driver. You can see shadow of the other car.
Beside, Camaro driver was drunk and didn't have license either. He got arrested with multiple charges, rightfully so.
Drive safe on public road. Don't act like you own the road.
