Tesla and many other cars already are able to move the steering wheel with software. So, you don't need steer by wire to have this functionality. Even in basic self drive mode, Tesla will do all the steering for you from their software to the wheels.

Just to make sure that I understand you correctly. What you're saying is "trust them, they are from the government?"

:D

Steering by wire suprises me exactly 0%. Those of you who mess with rc aircraft or planes know about alot of the advantages, variable ratio curves, exponentials, automatic stability and counter steering. Hell sport mode may actually do something real in many more cars.

It will be good for 98.2% of drivers who meet the following criteria: don't work on their own cars, and don't care much about drivers joy. The rest of us 1.8 have already been screwed on these factors and it will continue to get worse.

Decent steering died about a decade or so with EPS anyways. Steering feel is one of the things I really miss about my lotus now that it has been traded for a cayman gts. I am told the cayman has one of the better eps systems, but it isnt even on the same planet as the manual lotus rack.


Thankfull for us enthusiests alot of decent sports cars were built between around 1995-2015 ish, hopefully the supply doesnt run out in my life time.
I will say that when I joked about mustangs benefiting from it, I was a little serious. Most oversteer situations (any vehicle) end poorly because of inadequate amplitude or inadequate speed of response. If the car could counter-steer itself, many, most of those issues wouldn't end up the way they do.

I will admit, I preferred the feedback of my old '88 (brakes and steering) to the feedback from my Boxster.

I am of two minds on this but need a lot more information: a FMEA so to speak.

I did a lot of them in flight test...ok, I didn't but the smart folks did:cool:

People I know who are on their 2nd Tesla love the self backing out of the garage. She uses a walker and he has a Cayman. It's difficult for her to enter the car from where it's parked in the garage. So she has it back out and wait for her.

What I am getting from this is, yes, it is a moot point

You seem to think everyone can run a steering wheel. I'm going through this very thing right now with a daughter who can't. So, if you're going to insist on not understanding a situation, that's your issue. As for the other asshat, don't you have toes to smell?

Yes, Tesla and other cars can do the steering. But if that steering fails, there's still a physical wheel that's mechanically connected to the front tires that allows you to steer the car (or if the car is not running or has had an electrical fault, dead battery, etc...)

Right, drive by wire (whether via a wheel, joystick, cell phone, whatever) will potentially be a boon to folks that would have a problem with a standard steering wheel.

Surely there are adaptations (and have been) to enable those folks to drive a car with standard steering, right?

I've never been in that situation, so I don't really know much about it. I've seen videos here and there that showed various adaptations, but the only specifics that spring to mind are hand controls for the gas and/or brake. I can't remember seeing any adaptations to replace a steering wheel, but I would assume that's just because I don't have any direct experience.

And if there haven't been, I would think there would be now when you consider how many vehicles there are that can steer at least to some extent.

But, I would think that steer-by-wire wouldn't really be much different or easier to adapt than my wife's outback with lane assist or a Tesla that is self driving, both of which have standard mechanical steering.

A few race cars equipped with steer by wire have been run at the Nurburgring 24 hours:

Driver feedback is one of the big adjustments. The system can be set to filter out some of the feel that comes from bumps and curbs.

Here's more tech information from the company that makes it:
