What even happened here?
Looking back at the video, it's clear-ish that something is hanging from the bottom, and somehow the driveshaft ended up grabbing the rails.
It's almost as if the car saw an opportunity and then willed its destruction into existence. But that would require cars to become sentient, and we all know that Pixar's vision of the future is entirely fiction... right?
Point is, this driver drove this junker over a railroad crossing and he probably should have know he wouldn't make it. The results speak for themselves; know your limits or bear the consequences.
