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.
