Switch to manual brakes makes car run better?

My wife got banned from riding with me some two decades ago.
I got sick and tired of hearing her chirping as regards her neck getting a workout, no matter how gentle I drove; and she being almost 4 years my junior, sheesh.
Not to mention her right foot constantly looking for a brake-pedal, sheesh.
Or
the more than once she instinctively reached for the steering wheel, double-sheesh!
Or
there's no radio, the car is too loud, or too rough, or too something; fine
then stay home ....... darling........................... don't wait up, honey.
