Power assisted steering is suppose to give you better road feedback than full power steering. Many US luxury cars have full power steering and you can't feel a thing going fast thru a corner. No feedback to help you realize you are going too fast. With power assisted, you will feel greater wheel pull back to center the faster you go. And if you hit a slippery patch in the turn, you'll know it. MUCH BETTER SYSTEM!! The MDX road feel is pretty good.
