A new OTA update rolled out to Tesla Vehicles in the days before Christmas, and wouldn’t you know it – there was a hidden Easter Egg built into the update. Last year, we had the synchronized light show on the Model X, but Musk went a little more complicated this year and replaced the Model S on the main display with an image of Santa and his sleigh. It went even a step further with cars shown on either side being replaced by reindeer and the turn signals being replaced by Jingle Bells. If you haven’t accessed Santa Mode on your Tesla yet, it’s not that hard. Just access the slider or say “Ho Ho Ho” through voice command and you’ll see the fat man himself pop up and prepare to guide you through traffic.. or uh… reindeer that is. Check out Elon’s tweet, a couple of images, and a video showing it all down below.
