I love the light show (aka easter egg - we had a relative working at Tesla and they would hide "easter eggs" with codes for these types of entertainment), Santa's sleigh, music creatiion and more. My friend pulled up a few days after Christmas in his one-year-old Tesla and I asked him if he checked out the new software and its features. He said he had those feature one year ago when he bought his car. What is up with that? Why would Tesla hold that back for earlier versions? My Model 3 is a 2018.
