Neither of those are a problem in my 2015 Tesla Model S for the buttons that control the climate control or media player.
replyIt seems to me that many of the problems that people report related to touch controls are more to do with how they are laid out than the fact that they are touch controls.
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.
replyFloating 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)
