Of course, we don't know "the rest of the story", yet. And the train was traveling rather slow. And the adjacent field looks like a nice soft landing area. And it's adjacent to a road for relatively fast/easy response and recovery.
But, if those roly-poly tank cars maintained their tank-integrity and held their contents safely through it all, then kudos to their design/manufacturing.
Just looking for the positives.
OTOH, they might want to heed that flippin' tie at the crossing! It could've punched a hole in the passing car and created a much, much worse ending.
Kudos, also, to the vehicle driver/passenger/railfan? who happened to be recording the event. I hope he/she is rewarded handsomely for providing great documentation!
