Breakover and departure angles for work vehicles are practical considerations when taking vehicles off of pavement even if you aren't trying to cross the rubico

Breakover and departure angles for work vehicles are practical considerations when taking vehicles off of pavement even if you aren't trying to cross the rubicon, and those angles are determined by heights relative to lengths so as one scales up, so too do the others. This is similar to how boats get bigger in every dimension as they grow in length -- you don't just make a boat longer without also scaling up its width and cabin volumes.
