For S & X owners, consider the amount of time it takes to press the voice button, wait for it to be ready, say "open glove box", have it process the command, and then finally open the glove box.
Then consider how long it currently takes to just reach over 2' and press the conveniently located open glove box button.
Why would you want a voice activated glovebox? This is one of the small things that makes me not want to buy a Model 3.
