Hi Neal,
I was thinking about it this morning and the Prius has two built-in advantages:

1) MG2 - goes forward and reverse and can operate as a 'brake'. It is fully computer controlled.

2) Electrically assisted steering - Toyota only needed to add left-right steering commands and it no doubt is strong enough to handle low-speed steering requirements.

All that would be needed is a vision processing system connected to the existing backup camera, possibly a front sensor / camera and connetivity to the hybrid vehicle ECU and the steering assistance unit. Of course there would be a 'ton' of software but everything else is built-in to our computer controlled Prii.
