I hate to be the bearer of bad news but this isn't unique to just the dumpster truck owners.
I've seen people try to drive away with a couch mounted vertically in the passenger seat of a convertible (with no straps or rope of any kind).
I lost track of how many people roped their doors shut through the windows on their vehicles while strapping a 75 inch TV down to the roof of their Honda CRV.
The general population has an unbelievably poor understanding of physics and honestly I think we need to let more people die due to darwinism again. Saving the village idiot with modern medical standards has really just allowed them to get older and come up with even worse ideas. Sometimes they procreate and spawn in some new physics challenged shitlings that will be finding their way into your local ER with some self inflicted stupidity any day now.
