You might be surprised how low the clearance is on some over-the-road trailers. Especially the long ones for hauling heavy equipment, their breakover angles are atrocious. Most roads are navigable regardless, and they know how to pick routes that avoid impassible ones. Low as it is, this truck's clearance probably isn't as limiting as you might think.
Not the OP but I know the feelings about the Citroen BX - it was just such a drab design, looked like a shipping box, and was just generally a dull car to be around. Best feature was its suspension, which would lift the front end up during acceleration until it got to a 'settled', floating position .. that always kind of felt like doing light speed in the millenium falcon or something similiarly odd in a very, very boring car.
