"According to the manufacturer, this electronic system’s input is actually faster than a traditional, mechanical one."
Well, if you can hypnotize yourself into believing that a normal steering gear, mechanically connected from steering wheel, through the shaft to the rack, itself connected to the steering knuckles on the front axle hubs, can be slower than some fly-by-wire system acting on solenoid actuators after interpreting tiny steering wheel movements from a potentiometer, then sure.
Man, as a mechanical engineer, I just get so annoyed with the utter BS we get fed by PR nitwitz.
Although maybe Nissan normally uses large rubber chunks to join the steering wheel to the shaft. That would explain the euphoria of the Nissan development engineers for FBW steering,
