Coat hooks - why not.
Grab handles - why not
Apple CarPlay - definitely Android Auto as well.
Siri Hands Free - All other voice recognition "operators" as well
Hands free text messaging - read-a-loud is definitely doable. Though speech recognition for answering also possible.
Memory passenger seat - depends. If seat servos have positional memory (expensive) then it is just a software upgrade
Adjustable headrests - Security problem. Most car manufacturers are moving away from adjustable headrests as majority
ignores correct positioning. Therefore either automatic or one-for-all solution is better.
Memory seat settings and adjustments on the door - Memory seat is available now AFAIK. Adjustments on the door makes
things too complicated. Idea of memory is that you set it and forget it. No need for buttons you use once a month.
Way points on Nav - definitely, shame that they still don't have that.
Easily accessed Recirc button - doesn't Tesla have automatic recirculation according to air quality outside (sensor?)
Roll out pano roof shade - one of the things that I have suggested like gazillion times.
A well designed center console - it's getting better
BLIS system - what about solution below? Would that work.
A place to stow the tow hook - weird, a special styrophone block is enough (trunk in the "kids footwell" compartment).
Actually, it should be mandatory as no OEM equipment in the vehicle is allowed to be "not secured".
A radio that will turn off - today that is not possible as there is no classic "radio". It has other functions that must be kept active.
BLIS. Though Tesla has some weak warning, that is definitely not appropriate.
I would suggest them "triple-level" BLIS:
Level 1: faint orange if
vehicle detected and car not in autopilot (manual driving)
Level 2: blinking bright orange if vehicle detected and
driver switched on turn indicator or is too close (70cm?)
Level 3: blinking bright orange with rapid beeping (optionally steering wheel torque in opposite direction) if distance
is way too close (less than 40cm) or 50-60cm without turn signal.
