I have so many questions...
1. How do you not see this out of your side mirror if you're the truck driver?
2. There's obvious noise from the tires skidding, you don't hear that?!
3. THERE IS A CAR ATTACHED TO YOUR TRUCK! Did the added weight after the COLLISION not make you second guess anything?!
Unreal. Someone take that dude's license or get his ears checked, SOMETHING.
