its a vehicle with more interior space than your house. Its two busses fusing their commuter powers to form a transportation super-entity. Its a hinge that does not somehow buckle completely underneath the pavement-ripping levels of tourque needed to get two bus chassis moving. Its incredible.
Its easy to write off everyday feats of engineering prowess like the articulated bus, but I swear, there is nothing like watching 70+ people line up to get in it, and watch it swallow and seat them all like some kind of comfy mechanical whale. Its a land battleship, refit for civilian duty. If I win the lottery, I'm getting one of these things, covering it in machine guns and armor plating, and riding out the apocalypse with 70 of my closest friends.
