FSD Beta still runs on the old fork of the Tesla software, and nothing "good" has been merged into the newer branch that I'm running (the one that supports Apple Music), and on long road trips, the phantom braking (which I've surmised happens mostly on undulations on a rising or falling road) is still a huge bother/risk... and the fact that Tesla hasn't back-ported whatever fixes they claim exist for phantom braking with AutoPilot means.. it doesn't exist yet. And it's been a problem for years and years now.
Also, my Tesla on AutoPilot freaks the f*ck out in large suburban intersections where the roads all go very straight -- it'll jump from lane 1 to lane 2 in the middle of the intersection. Not sure if SF has big intersections of the sort I'm talking about, but Sacramento, Reno, Las Vegas, Phoenix, and LA certainly do. Again, something they could fix if the fix was real, and for all the drivers out there smacking their stalk and AutoPiloting.
And lastly, on the highway, where the right lanes expand and contract with onboarding and exiting lanes the car tracks to the right solid line and not the un-moving dotted line to the left of the car. So the car is constantly jumping left and right as the "center" of the lane changes (because the width of the lane is changing), when the lane expands to allow for merge-lane traffic from those entering and exiting the freeway.
Two of these examples are on highways, which are ostensibly easier challenges than city streets.
Where's the rapid evolution of the tech? Not in product scope of the features people with Teslas are using day to day.
