There's 5th wheel hitches that do this, most manually slide, but some do it automatically while turning. I've often wondered why I've never seen such an arrangement for semi-trucks. Small gap on the highway, larger for turning.
Here's an automatic one.
(Not a 5th wheel guy myself, maybe someone who tows a 5th wheel can add some details?)
