Push-button gearshift is different than what the article mentions: no gearbox. There's no shifting which means everything is way smoother. Also, engine noise is only a feedback mechanism because we rely on it. If it was eliminated overnight, then we'd have to rely on other mechanisms (probably tire noise). Tire noise is actually dependent on vehicle speed, unlike engine noises. All engine noise really tells you is that something is there, or that something is trying to look like/seem like it's accelerating fast (from high revs). Not really a lot of information you get over tire noise. I'd love to be in a place where all engine noise is eliminated. That being said, just as another poster mentioned, the bigger challenge is tackling heavy vehicle noise concerns. For the most part, cars today are quiet in comparison. I just want semi trucks/dump trucks/delivery vehicles to be quiet since they tend to be many orders of magnitude louder than regular cars.
