When I first drove my Mazda, it has PS, but the fluid was dry, so it didn't really work, so I had to put my arms into it. Wasn't so bad as the Land Yacht without PS... when it would stall while moving and I lost PS, it took a LOT to steer that 5,000 pound monster.
I've only driven the baby without PS once, when I stalled going downhill (It was like my first time driving it, now I'm almost as smooth as butter), and it was alright to drive.
