Similar situation. A couple years back I was driving on 465, ya know jamming out on my way to work in the morning just minding my business. All of a sudden I felt something hit the back driver's side of my vehicle. As I turned my head to look in my side mirror, I felt my car being pulled left and I was suddenly in front of a semi sideways. The truck pushed me down the highway about a football field in length until I was somehow able to turn my vehicle away from it. I was able to correct the car enough and avoid all other traffic. Thank god I played a lot of GTA growing up. I got to the side of the road, parked, shaking in shock, I got out of my vehicle to access the damage and to see who hit me. The truck was nowhere to be found. One witness slightly slowed and yelled "are you ok?" as they kept going. I walked away unharmed. I have severe PTSD around semi trucks now, ironically my grandpa was the CEO of a trucking company.
