Nothing is absolute except death and taxes but mechanical automotive steering has proven to be very robust . And not failure prone . Electronics on the other hand can fail from moisture or rodents as examples .

Comments above stating handicapped folks could be helped by steer by wire are good points . But I have to think a very small overall number . But still a valid point .

Exactly, planes have been fly-by-wire for a long time, but planes are expensive and have multiple layers of redundancy.

I feel like most cars these days are built to a price and then everything non-essential stripped out.

For steer or brake by wire (in many ways, far more important than throttle) you'd need multiple motors, systems, servos, pumps, etc.... to ensure that the likelihood of a failure is practically nil. And on top of that, most planes MUST be maintained to a MUCH higher level than most cars.

I feel (no evidence or expertise to back it up) that truly safe, robutst steer or brake by wire in a car would be an expenisive proposition.
