Prolly cuz when hoverboards were first "invented", they acted like skateboards, but hovering instead of wheels
I've seen variants of it, too
Some require metal underneath to work, so common areas have a metal gridwork system underground
Some can go anywhere, have their own special thrusters to keep them aloft
Course, both have their own forms of weaknesses
