Sort of like this oversize load, which is attempting to traverse a fairly large roundabout. Now obviously, the larger the diameter of the roundabout, the easier it's going to be for a semi to get through, but even this big traffic circle is a challenge. It looks like the trailers each feature their own steering system, and it seems like they can actually pivot independently of the truck's payload (anyone familiar with oversize loads, though, please share your wisdom in Comments).
We have video of the process down below. Have a look and let us know what you think.
