Reminds me of the time when my uncle asked me to go get the dolly from his garage. I, being a kid and having no context for why he’d need a dolly, spent a few minutes in his garage but eventually returned with a Barbie doll still in its box. Fortunately, my uncle just chuckled, clasped my shoulder, and went to the garage to get his dolly so he could move his laundry machine.
I often remember that day as a lesson in humility.
Wheely transporter? Everyone I’ve ever known has always called these "dollies". Maybe it’s just an American thing. Also I actually looked up dolly to get this image.
It's an American millennial thing. From the folks who brought you boaty mcboatface and heckin puppers, it's the "half of our humor is using babytalk out of context" generation
Probably to allow for a heavier load (clustered) and for keeping the dolly on rails (tilted) although the rails seem proprietary, not something you find just everywhere
