You have to spin the magnet on the truck real fast to turn the force acting on it into rotation. And the other magnet needs to be an electromagnet. Ok, so you need two donuts, one a web of copper, and the other a liquid conductor like gallium. And you need a big computer. And more drugs. We always need more drugs.

How about take a toriodal magnet, mount it perpendicular to the ground, lower the magnet until it rests on the ground, then spin the magnet.

You could turn the earth under you, and get wherever you need!
