power steering is force multiplier, makes it easier to steer.

but along the way companies cheapend out the power steering, mostly the
pump, and it is less reliable, in some cars not replaceable if it
breaks, you can only get another from a junk yard and put it in, but it
is just as bad, plastic tanks that crack....
