T-MUST, or The Mostly Useless Trike, was the epitome of late Earth engineering. Carl von Hammersmarck built it with his father's money when he drunkenly bragged that he could sell anything to "the stupid 98%". "Oh yeah?" his friend blurted out. "PROVE IT!"
Carl did by building the most impractical vehicle to ever drive the roads. It's main marketing point is the off road capabilities, but the target market segment would never dare go outside the city. It's to wide for a standard road, and the T-MUST guzzles fuel.
Naturally, Carl (and his father) became even richer selling the worthless piece of crap at a premium price.
