Well, at some point you won't have a choice. The government is going to ban ICE vehicles, tax the existing ones, and all the electrics will be everything by wire.


There is literally no relationship between propulsion tech and steering mechanism.


I for one cannot wait for my nuclear powered steering mechanism. The reactor is of course used to generate steam pressure to actuate the steering arms, the car is powered by normal batteries.


Which ICE vehicles are completely steer by wire?


Not steer-by-"wire" exactly but in the 1970s and 1980s Citroën had cars with "DIRAVI" steering. In normal operation there was no direct mechanical link between the steering wheel and road wheels. The whole thing was a big hydraulic servo, with "resistance" applied to the steering wheel using a heart-shaped cam, a big spring, and a small hydraulic piston that had progressively more pressure behind it based on road speed.

If you let the steering wheel go it would spring back to the middle even with the car at a standstill because of the resistance cam.

If it lost hydraulic pressure while you were driving there was still generally enough in the system to allow you to pull over safely, and you could drive for much longer distances if you could cope with about a quarter of a turn of "play" in the steering wheel. With no pressure at all, turning the steering wheel would move the shuttle valve in the steering controller until it bottomed out and then the linkage would just turn the pinion on the steering rack, which was normally used for servo feedback. Uncomfortable, but acceptable for "get off the road" situations.

The hydraulic system also worked the self-levelling suspension, the fully-powered braking system (similar to the WABCO systems on a lot of more modern vehicles), and on some manual gearbox models the clutch.

Not really "drive by wire", because it's not electronic, but it really is a system where the steering rack could be fully decoupled from the steering wheel.


The Infiniti Q50 had steer-by-wire with a backup steering column that was disconnected from the steering wheel in normal operation.


Which EVs are?


You are being downvoted and the replies so far aren't helping you understand why your statement is very wrong.

"Steer by wire" means there is nothing but copper signal wires between your steering wheel and the front wheels. Your steering wheel is essentially a video game controller.

This has nothing to do with the car's mode of propulsion though, and both EVs and ICE cars can have steer by wire controls. So far, it's only the cybertruck that has this paradigm, all other EV's all have normal power steering.

For normal power steering systems there are two types: hydraulic and electric. Both types have a solid steel shaft between your steering wheel and the front wheels. You can remove the engine/motor completely, and you'll still be able to steer the car. The hydraulic or electric motor merely helps you turn the wheel, nothing more. Hydraulic is being phased out for electric in both EVs and ICE vehicles.


Steer shafts are being phased out. Electronic power steering has nothing to do with what I'm talking about. Manufacturers want fully electric, fully autonomous cars. If the computer is driving the car 99% of the time, they'll argue that having a steering shaft is totally unnecessary.

For whatever reason, manufacturers aren't trying to make fully autonomous ICE vehicles.


They are making autonomous ICE for the one scenario they remain the most practical for: long-haul trucking.

Driving forces could be interpreted as wrong, but they’re probably correct about orders and outcome:

Step 1 is policy/goal for California [1].

Step 2 decades old policy in Europe (and recently canceled in Canada?), as vehicle carbon tax. There’s also EV tax credits of course, which are practically identical, from the purchasing perspective - “If I buy ice, I pay this much more in taxes”.

Step 3 is a potential market driven eventuality.

2035 in the EU, if nothing changes, will be the end of sale of new ICE passenger cars. It's not that far.

(Technically they will not be banned, there will only be a huge fine for the manufacturer for each one sold.)


Sure, but this has precisely nothing to do with steer by wire.


What do you mean? Many places are already banning or heavily taxing new ICE vehicles.
