electric power steering

[Steve Hirsch]

Thought I'd pose this here while the list is enjoying a spike of activity. (That and I'm not really 
active in any current forums.)

The general conclusion I draw from reading reviews and approximately zero experience is that 
electrical PS systems suck because they lack feedback. This seems to be the case across segments, 
whether the cars be sporty or appliance.

I've been struggling to understand why.  C&D did a article on this a year or 2 ago but it didn't 
really help me much.  As I understand it, hydraulic PS systems use hydraulic pressure to push the 
steering rack in one direction or the other when the rack is off center, and when the rack is on 
center then the system pushes neither way.  Why can't electric systems produce the same type of 
assist?  Why are they necessarily numb?

Feel free to ignore if this is too much for one day!  :-)
