I am disappointed with Toyota to only have one tether restraint in the 2nd row. So if you have two small children in car seats they both can't be tethered in the 2nd row. Also the placement of this 2nd row tether is terrible! it interfears with the person in the 3rd row, their feet get tangled in the tether. Not safe!!! dt.
