Let me put it this way:

They are scaling up to a CAR--like the DARPA Grand Challenge or a Google whatever-they-call-it. No car on the market today has a holonomic or swerve. None. (Besides maybe a self-park feature, but most of that is done with the car steering itself.)

Therefore, a driving requirement of the design is that it has to scale to a CAR. Leaves Ackermann steering--and the basic design shows their steering mechanism.
