This update is not being pushed OTA. You'll have to visit a service center if you want it before the next more significant OTA.
Had this confirmed by a few different people at Tesla.
Not worth bothering Tesla for, imho. Although I think they fixed my rain sensing wipers...
There's some newer update than 2.9.40 (which I have); had a tech come out to fix my car today and he said a new one came out yesterday so he threw it on my car (will download tonight, but I'm a little nervous that the restrictions on AP are in it, so I'm thinking I might wait...)
