I think Tesla is doing 2.99%. I could be wrong
Time for another prediction
You get your VIN this Saturday night and get a delivery date of 29th.
Best thing to do is call the SA and preemptively schedule the delivery date for Monday. The car will be still in transit and they will assign a soft delivery date, so you wont have to worry about it.
Dont worry too much about this thing mate. You got a new amazing car. Enjoy it. Have fun with it. Dont let the whole matrix lights discussion get you down. A month ago 70-80% of the folks here didnt even know what matrix headlights were, and 2 months from now, people coming to this forum would not know about about matrix headlights either.
Right now the reflector and matrix are exactly the same. Maybe 2 years from now, Tesla might start adding them to Model Y LR and SR and then they might think about bringing in new software to leverage them. Till then you arent missing out on anything. And even at that time, you could potentially just reach out to SC and get them retrofitted if need be.
