You'd thinks so, right?
After all that's the "promise" of OTA software updates.
Reality is, they don't change clearly bad stuff after 3 years. ... and counting.
Stuff like this often never hits the radar, or falls off the bottom of "interested" pile, or whatever... just be prepared to never see better vent controls and be happy with what you see you're buying. However, there is no sure bet that things will stay this way and won't change for the worse.... Tesla sometimes makes "improvements" that ... aren't welcomed by many. Brace for poor vent controls getting even sloppier one day when nobody saw it coming.
Many of us think that the dudes don't design / think / develop / test this stuff in real cars until the beta is upon us.
