I get that seeing the tachometer is important for manual cars, but I drive an automatic. It exists, but when I drive I never look at it. So why are they on automatic cars?

There is no need for it, my first car had a nice large clock instead. My current car, an EV, also has no tach. https://i.imgur.com/eG6TlQT.png
However, race cars always had a nice large tach, usually in the centre. So as cars got sportier, they started getting tachs too, to seem more sporty.
Now cars have big digital screens, gotta have something to fill all that space.
You should be aware that a lot of the gauges on your car are fake. The temperature and pressure gauges will the middle if everything is “ok” and off the top or bottom if things are “bad”. In reality they should be wiggling around as you accelerate and drive hard or easier or the weather changes. They could easily be replaced with an error light.
