Electric steering is power steering using electric motors instead of hydraulics. There is still a physical linkage and you can still steer the car with the power off.

On my 2014 Prius, the brakes use an electric pump to power the hydraulics. In normal operation, the computer handles the brakes, but there is a physical backup.

The throttle is completely by wire, because there is no more reliable way to run two electric motors and a gas engine together with an analog system.
