The ultrasonic sensors work for close up blindspot detection but they are useless for seeing that car coming up fast behind you or coming up fast in an adjacent lane. You MUST have rear and side rear radar to do proper blind spot detection. All modern cars that do this like Mercedes have all around radar for blind spot detection.
Who uses radar for blind spot detection? Everyone uses ultrasonic.

Why does blind spot detection need to see cars coming up fast behind you? Those will be visible in the mirrors. The blind spot is only an issue for cars which are near your speed.
Obviously, the car needs to be able to detect such cars in order to change lanes by itself, which is why lane changes require driver intervention with the current hardware. But plain blind spot detection doesn't need it.

I know Subaru now uses radar for their Blind-Spot Detection. I'm sure there are others as well.
This is already 3 years old and even back then the sensor suite was far more enhanced than Tesla is currently:
Sensory Overload: How the New Mercedes S-class Sees All
Really? The release notes page says this: "Advancements in signal processing use the Tesla's onboard radar to persistently capture snapshots of its surroundings, creating a 3D picture of the world. Learn more about seeing the world in radar."
The radar processing only applies to the front view. They have improved the resolution on the radar so it can give AP more information. Sonar is the only thing available for rear.
7.1 --> 8.0 sounds like a big change, but overall it's 90% the same codebase.
The biggest changes percent wise are AP and the media player.

Release notes say:
(2) Is there a clouds sensor?
(1) Can someone explain this for me? What does the sun-angle knowledge add to a thermostat system?

Hey Everyone, long time lurker but now have some time to actually get on here, got 8.0 posted a video of the media player posted at the bottom of this post, I have some other videos I made early this morning but will post them later when Im out of work. In the meantime see below.
Its definitely a step back in terms of ease of use and quick access to things, you need to tap the map to see the control bar, but it only happens for the map. Other apps have the control bar in full view at all times.
Didnt see anything about off ramps in the notes, but could have missed it. I will try it later today and report back.
Nothing in the notes about Waypoints or how to set them, but there is a new view for "legs/segments" of a trip that allows you to see individual legs/segments versus the entire route, this was done automatically prior to 8.0 this gives you the option to choose the view.
See my video below, no Apple Carplay or Android Auto, but just an updated in-house media app. USB navigation has been updated for the better except the removal of browsing by name via the alphabet scroller on the side, now you need to scroll and scroll and scroll to get through the list.

Much like "snippiness", there should be a "old speculation bin"
Most of the content on this site would be in it

I wouldn't try to extrapolate too much from a sample of 9 or 10 cars out of 100,000. I'm pretty certain there's more than that in the beta group alone.
