Any urban cyclist can tell you - even the smallest, two-door coupes can seem monstrous while they're three inches from your handlebars and whizzing past you at forty-five mph.
So, the possibility of this 600-pound, four-person-powered bicycle (quadcycle?) that can roll over a car is certainly...interesting.
The Big Dog is "a wonderfully impractical assemblage of bicycle, go-cart, and golf-cart pieces and parts, drainage pipe, steel tubing, and patio chairs. This four-wheel vehicle allows four passengers to travel in minor discomfort at speeds approaching a brisk walk, for relatively short distances, on completely flat terrain."
