You are displaying your ignorance of trucks. For decades now, all automobiles and trucks have included proprietary computer systems. Some are easy to hack and alter. Some are more expensive/challenging, but people do it. An EV is missing _most_ of the mechanical parts that defined a "truck" for a century, and is basically only four tiny motors, brakes, a computer system, and a battery with wheels. The sole characteristics of "truck" that still remain which Henry Ford would recognize are "has wheels" and "can carry cargo".
