Going from four stalks to two was an improvement. Using the gear selector for AP was a master stroke; there's virtually never a time when one must use shifter and AP.

However, inability to adjust speed via stalk is a big step backward. And, using upward movement to turn off AP can lead to inadvertent shifts into neutral. (It's happened to me twice ... despite being hyper-alert to the possibility.)

Fix is simple.

Keep existing right-hand stalk.

However, use the same underlying switchgear as left-hand stalk (which allows both vertical and horizontal movement).

Adopt same AP stalk mode as Models S and X:

Horizontal to trigger/stop AP (one flap out = TACC, two flaps = AP, push in = off)

Vertical to adjust speed (first notch = 1 mph/kph, full movement = nearest 5)
Hardware cost should be minimal. Retrofit labor (for existing < 10K cars) should not be excessive.

Solves adjustment gripe.

Solves inadvertent shift gripe.

Makes transitioning S/X <---> 3 much simpler and more consistent.
 
I think just have the first one (horizontal stalk activate/deactivate AP) would be a huge improvement. I really don't see it happening though as I don't think they want to do any hardware swap, unless people start to have accidents because they accidentally switch to N and didn't know a 2nd down will put it back to D. I was actually practicing this on my MX yesterday. Driving on local street, put it in N, first down trigger a "ding" warning and does nothing, 2nd down put back to D. You know someday I may decide to order a M3... :D

Hardware part should be minimal. Keep same stalk. Use existing switchgear part from other side. Tweak software.
