If you just downloaded V8.1, tap the the T on center screen three times — Elon Musk (@elonmusk) March 29, 2017

Both HW2 and HW1 Model X have few new features as well, like the ability to lower the height of its Falcon doors (for parking in cramped quarters) and more adjustment for the middle-row seat. In terms of creature comforts for both the HW1 and HW2 vehicles the onboard Maps app will display more info about businesses including operating hours, address and phone number. Headrests can be adjusted now as well, and the vehicle will curate a radio station based on what you've listened to and given the old thumbs up to.

The 8.1 update is rolling out domestically today, with worldwide availability coming throughout the week. With this patch and the features that preceded it, we're seeing the steps Tesla is making toward delivering truly autonomous driving.

And being the nerd that CEO Elon Musk is, he hasn't been able to keep the existence of another Easter egg to himself. As Electrek reports, tapping the T in the center screen three times will open up a sketchpad. Handy!

Update: The article originally stated that Tesla's Autosteer worked up to 90mph, but it's only engaged at 80mph and below. We've updated it with the correct info.
