Only if you've memorized their locations. On my prius they made certain physical buttons have bumps because it's hard to tell which is which without looking at it.

I find the Tesla touchscreen UI to be dangerous. Basic functions require a glance at the screen. The only viable alternatives are multitouch gesture controls or voice recognition.
