Seems like a very strange move. The Tesla seems to signal a lane change and abruptly slow down at the same time on a highway with no lights, intersections, turns, or obstacles. This was precisely the type of driving I figured would be easy to automate - rather than deal with urban settings, pedestrians, bicycles, etc.

Tesla's systems sometimes see phantom obstacles (e.g. shadows or reflections). Trying to change lanes away from them and then braking when they cannot isn't unusual at all. One of the reasons it is surprising regulators let this "beta" test be conducted on public roads with other drivers who weren't asked nor agreed to the disclaimers.

    yet they have radar and 12 long-range sonar sensors

      They actually removed the radar and ultrasonic sensors for model years 2021 and onward.

The problem of driving a robot straight through a corridor while avoiding obstacles is Robotics 101 stuff. With the right sensors. This scenario calls for long rang distance detection, which is the natural wheelhouse of LIDAR. Unfortunately, Tesla seems to have something to prove when it comes to LIDAR, and stubbornly refuses to adopt the technology, despite crashes and even deaths that have occurred, and general industry understanding that it's the enabling technology for driverless cars. Is it legal to create a two-ton machine with admittedly beta-quality software, and a sensor stack that is known to be insufficient; and allow it to autonomous roam around town, crashing into things and killing their drivers? Apparently that is fine in the eyes of the law. Is it unethical? Society seems to be deliberating this one. I hear a lot of "the ends justify the means" style thinking in this area. Either way, this should embarrass the hell out of Tesla engineers. I used to feel sorry for them, but it's been long enough that they should know better.
