I was under the impression that electric power steering was to eliminate the weight of hydraulics/pump/steering rack and parasitic draw of the pump. So economy/mpg was supposed to be the original reasoning.
But yes I can see where they were going with the computer-controlled steering.
Yeah, that's how they sold it. I never bought any of it. It was obvious from the get-go that the MPG argument was bogus -- there's no energy (fuel) savings driving anything with electricity over a straight mechanical connection, unless the thing we're talking about can be shut off, and power steering is always on.
Electricity isn't magic, it comes from somewhere, and that somewhere is the alternator, which is driven by the engine, which is burning fuel. More electric goo-gaws mean a bigger alternator and battery, with all the parasitic losses involved.
As you know, in a traditional system the engine drives a power steering pump which makes a fluid connection to the rack. With an electric system, the engine drives an alternator, which charges the battery, which powers the stepper motor, which helps the rack steer the car. You can't get more out of something than you put into it, and power steering is always active.
Making the system "save fuel" would mean that we've invented a perpetual motion machine. The conservation of energy is a thing.
The end game was always a push towards some level of autonomy.
Regarding the "feel" -- I divide vehicles into two clean classes: fun cars and work mules. Keeping the classes clean makes dealing with them much easier. In a fun car, I want as close to an analog experience as I can tolerate. I like driving the Speedster because it has no power-steering, no power-brakes, no automatic transmission. I give the car inputs based on its feedback, and the whole thing is enjoyable.
It is not a work mule, though. My work mules have a job to do. Jeanie's minivan moves little people around conveniently and comfortably. They watch movies in the back, play games on screens, and everybody in the vehicle can travel for hours and hours and hours on end without feeling like the car is fighting. I can easily drive it to Denver (1000 mi.) and arrive happy and ready to rock. I couldn't care less about "feel" in the minivan, unless what we're talking about is isolation (or a lack of feel), in which case I'm a fan. That minivan is a floating living room, with "float" being a positive adjective in this case.
Electric racks and all manner of electronic frippery do not diminish this experience they enhance the primary objective. As a point of fact -- when the infotainment system glitches, and we can no longer watch Wreck It Ralph on the screens in back, there is a near-mutiny.
My monster-truck is a work space. I'm not looking to find the apex in any bend -- but I really like that the truck senses that there's a trailer back there and tailors the shift-map, etc. for it. Backing up to a trailer to hitch it is a complete non-event with a nice backup camera. I still use my mirrors to back (van, truck, or truck/trailer), but Jeanie uses the backup camera anytime she's backing out of anywhere. It's pretty nice.
Do I worry that all this stuff will break? Absolutely. Do I think any of it belongs on a sportscar? Absolutely not. Do I want my work mules to behave a little bit like a sportscar? Not really -- I have one of those. I mostly just want it not to break, and to do what it's supposed to do.
Vehicles have different purposes. When we ask them to do things they aren't good at, we get Lamborghinis with automatic transmissions and electric steering.
