They're at the bottom of a portrait screen (and IIRC there's a bit of a bezel to rest your hand on), which makes it a little better.

Floating screens make this harder, especially as they get larger and further from the driver

Tesla has also been guilty of some particularly awful designs on later models, like requiring the driver to navigate to a submenu to turn on the wipers (which I know they changed in an update, but still should have never done to begin with)
