I feel the front passenger seat is the safest place in a PC for a baby seat. I would simply set the seat all the way back to clear a deploying airbag. Roll-over protection is best there and is least suseptible to flying objects. My 2007 does not have an airbag turn-off switch. Does the 2009-2013 have one?
The second safest place is the barrel chair with "D" ring achoring. Actually not the barrel chair, but rather a 3rd front seat type as we have here seen to the right. Like the barrel chair, it faces any direction, locking forward and sideways. But it's high back is a natural shield to flying objects thrown forward. It's nice to have 3 people able to sit in such close proximity to enjoy conversation and such. That 3rd seat works nicely for it.
More recently the 3rd seat has been replaced by a euro chair, but I don't know if it is safety rated with the mobility it offers.
