IMO, this makes for a bad user experience.  You don't want
to have to *think* about trivial little actions like this.

E.g., when we lift our *ringing* cordless phone off the
cradle, it automatically answers.  But, if the answering
machine has already engaged, you must press the TALK
button to be connected to the caller.

So, you lift the handset -- and *hope*!  "Hello?"
Wait a while to see if the other party is there.  If
not, they are undoubtedly speaking to the answering machine
and *you* just spoke to "dead air".  Quickly press the
talk button and reannounce yourself -- interrupting the
caller in the middle of leaving a message, etc.

Of course, it could be *worse*!  Imagine if the TALK button
served as the "on hook" (hangup) button, as well!  You'd
*always* be leary of pressing it for fear you *are* connected
to the caller and pressing that button would hang up the phone!

But, this other behavior rises to a level where you are
aware enough about it that it persists in your impressions
of the vehicle!  I'm sure Mazda would rather your comments
have been *unconditional* praise (regardless of how "trivial"
this other issue might be considered).

My old TV was a delight!  *But*, the MUTE function on the remote
did not operate independently of the other functions.  E.g.,
if you muted the volume and then changed channels, the mute
was canceled.  I.e., if you wanted to mute the TV and channel
surf without sound (e.g., maybe you or someone else in the room
is talking on the phone), you had to drive the volume all the way
down to '0' -- where it would persist as you changed channels.

So, in practice, you hit MUTE, changed channels, cursed because
the mute was released and instinctively hit MUTE again.  Paused
as you recalled the "decrease volume" trick.  Cursed again because
pressing Volume Down automatically un-MUTEs the set (again).
Wait for the volume to get down to '0'.  *THEN*, start flipping
through channels.

Again, the conditional endorsement of the product:  "a delight BUT..."

Sort of like climbing Everest and then planting the flag *in* your
big toe!  Sure, you remember the satisfaction of the accomplishment.
But, you also remember (and recount to others!) the hole you poked
through your toe at the time!  :-/  (which becomes the part of
the story that folks MOST remember)
