Navigate on Autopilot (Beta) suggests lane changes but does not proceed without confirmation. But autonomous lane changing is live in Tesla internal test vehicles and will roll out after more testing. Getting on and off the highway and changing lanes is a step up, so they are shipping real features.
They enhanced the cruise to be more aware of sharp curves (will adapt speed, even below your set point, in advance of a curve).
They also added blind spot monitoring showing vehicles behind and to the sides which had not been displayed on the guidance system previously. They also distinguish betweeen the type of cars with different icons for trucks, buses, and SUVs. They also added rudimentary pedestrian detection and a very goofy pedestrian icon on the guidance display.
And also dash cam support which had been much requested.
I agree with you that the media control from the phone is lacking. The good thing is I’m confident an update will come along one day and make it better. More than I can say for any other car!
Lastly, the humorous apps have a purpose. My 6 year old son is absolutely in love with the Tesla and now begs to take my car instead of moms Mercedes. He asks me at least once a week about when I’m going to get the Roadster with the rocket boosters. (As if!) It’s genius marketing even if it is a bit silly.
