with all the "infotainment" junk on new vehicles, plus the WAY OVERUSE of the cell phone, hands free or not, it's a wonder we don't see accidents like this more often.
i'm not assigning blame to anyone, but with the way the door is caved in on the mustang, it sure looks to me like it possibly cut off the semi.
for over the last 15 years or so, it seems to me the general driving public just doesn't care how they drive. jump in the car and go. if you are in my way, well here is mr. middle finger to you !
it's getting worse by the day................
prayers and condolences for the trucker's family and friends.
