Aerodynamics are secondary priority in vehicle designs.
Such vehicles are very impractical and I would hate to back up such in hard to see situation.
Take a look at semi trucks and highway buses. Back in 1970's they have been build rounded for aerodynamic reasons. In later years they make them square, because that what loads more cargo and makes money.
Even semi-trailer do have movable plates available on the rear, what improve greatly the aerodynamics, only one in a 1000 is using them.
