> Do you even want/need power steering assist in a runaway situation?

In my sole unintended acceleration incident (floormat) I was beginning (but committed to) a turn. I put the car into neutral and came out of it okay. (people forget that any modern engine has a rev limiter so neutral is really pretty safe)

It would have made a bad situation worse for me if I had lost my steering. I've lost steering on that car (lost the generator for a few seconds in the wet on two separate occasions) and I can confirm what someone else said about the steering getting quite heavy.
