Why not just steer with the back wheel? Then the suspension on the two front ones could be much simpler since it wouldn't need to include steering components. The back one is already mostly out of the wind flow, so minor changes to accommodate any additional steering related parts shouldn't make much difference.
Admittedly one would have to drive such a beast a little differently. For instance, to leave a parked position by the curb the car would likely have to back out. Going in would be easy though, stuff the nose in going forward, crank the wheel over the other way hard, and the tail slides right over to the curb.
