Heat Action Rear Head Crush - Waist high objects?

[nyaos]

Hi, I'm trying to do all heat actions and I'm stuck on the environmental Rear Head Crush. It says to grab someone from behind and then use heavy on a waist high object.

What counts as a waist high objects and where can I find them for fights? I've run all over kamurocho. Railings don't seem to count. I've tried a car too and it didn't seem to count (despite what a video claimed was the rear head crush move being done on a car).

Any help with this would be great!

Of course the moment I finally ask for help I figure it out- The trunk of a car works for this, not the door. Leaving this up in case anyone googles it in the future like me.

Thanks man, you're life saver. Going by the guide doesn't work.
