I'm actually very curious on what people think about Jr. having technological manipulation/technopathy. Throughout his many fights and seen with many vehicles, he's seemingly able to just stand around while his vehicles and machines fucntion seemingly without any buttons to input. In Sunshine, he summons Mecha Bowser from beneath the pool and floats over top of where he summons it, he can relax in his cozy cockpits in Galaxy and the mechs are capable of doing exactly what he wants them to, he can gesture and a floor will fall or the mechanical hand in NSMBU will mimick him and perform an action, and his Clown Car is very synchronized with his gestures and movements but he also can act independently too. In fact, many cases of the Clown Cars being piloted seem to show the pilot simply standing and not actually performing any controls. Iggy for example in Jr.'s Journey specifically has his hands on the rim of the vehicle but yet he's able to have it bash into people and move as well as stay stationary, and this one doesn't even have the eyes or face so it's not like it was sentient or an A.I. because you could make cases for that. But like, the Koopaling in NSMB2 all crowd the vehicle, holding their Wands in hand but the Clown Car is able to fly on it's own. The vehicles having sentience makes some sense, but how does it know where the user wants to go unless it's linked with the pilot somehow? This could give everyone possible limited technopathy. And the funny part if that Jr. in Jr.'s Journey DOES have a small remote thing with which he can summon a Clown Car, so you CAN operate these vehicles remotely, but in every case we've seen they don't need one.
This is something I've always wanted clarification on and to discuss with people.
