We often refer to cars as boxes on wheels, or we describe car design in terms of numbers of boxes: one for van-like things, two for hatch/wagon-like things, and three boxes for sedan-like things. With this common way of thinking, you may expect that a car that was a literal, no-joke box-on-wheels would be something that wouldn't seem so weird, or alarming. You'd be wrong. If you don't believe me, have a look at that Bubu 502 up there.
