Tesla aren't even talking about that, let alone offering any kind of roadmap for it.
Matrix headlights have been standard fitment on 3s since the start of last year, possibly the first MIC cars if not earlier than that, and sod all has happened with them in that time.
They've recently been made legal in the States, which I thought might result in an update "unlocking" this feature (since Tesla is certainly US-centric when it comes to development), but nope.
Tesla don't seem to have to bother with this stuff when people are buying the cars hand over fist regardless, so it's tough to argue against the logic of why they should be expected to enable it.
That all said, given how comparitively useless and lethargic even auto high beam is, can you imagine Tesla cracking the aforementioned active matrix functionality the likes of Audi, BMW and Merc have, where cars and road signs are blanked out, etc. Never going to happen.
