Your points are all completely valid and I'm not refuting any of them - I agree with you! But, for the record (Until someone at Tesla HQ decides to innovate something and moves all things around): Climate control/defog/defrost: touch the temperature display on the bottom left, a context menu pops up where these options are. Audio controls/mute: driver can use the left scrollwheel (up/down for volume, click to pause/resume audio), passenger can touch the volume control on the bottom right for the same. Locking: I really have no clue here. Mine does it automatically as I walk away, but that's due to the phone having the Tesla app running, and I wouldn't be sure how to do it just with the keycard. It definitely has a learning curve which other cars don't. Love mine to bits, but I'm not blind to the weirdnesses and warts (I just posted in this same thread a recent issue I had).
