It seems like it'd be hard to develop the torque for turning this way. Think of turning from a stop. If you lock one of the rear wheels, you effectively double the gear ratio to drive the other wheel, AND you're trying to rotate the vehicle around the single worst point as far as its angular momentum goes (if it's longer than it is wide like your sketch)
