A quick Google search of the phrase “push button transmission” shows pictures of car dashboards with buttons (admittedly not a keypad) with such a setup. Indeed, one picture is of the push buttons arranged in a circle in the center of the steering wheel. I would imagine that a new driver would not want to be heading down the street, see something they don’t like, hit the horn and suddenly find themselves in reverse.
