This drive was done with a 2022 Model Y Performance that has ultrasonics sensors, but no radar, and the FSD profile is set to "Average", and Auto Speed enabled. You can increase the playback speed, or just hit the bookmarks below for what I felt were relevant points.

My overall perspective of FSD Beta 12.3 is that it drives like a tourist. It is aware of how to drive really well, however, it doesn't know how to drive like a "local" making weird decisions with lack of "What's coming" or "This would be easier".

00:00 - The beginning/intro
02:07 - I think the car to my left was trying to race? Or assert dominance? Weird
04:07 - A welcome improvement. The car proceeds through a yellow, and doesn't tap the brakes due to car waiting, and moving, in the middle of the intersection.
04:57 - Doesn't pump brakes for car coming from the left, another improvement. Does brakes a little for blinky yellow lights
06:12 - Good merge onto highway. It signals, then moves over. Auto speed does not appear to work on the highway at the moment, so you can tell when it cuts to a different stack based on when Auto Speed turns off.
09:26 - Biases to left of lane with semi on right. I explain why I love/hate this behavior, largely due to narrow roads.
10:20 - I realize that the vehicle to my right has their phone out watching a video on it while driving.
19:42 - Biases to the left of lane a bit during turn, kind of weird and off putting, made me feel like I could cross by accident at some point.
23:39 - Skip heartbeat as I looked in rearview mirror and saw red/blue/right flashing lights and thought I was being pulled over. It was a tow truck
24:42 - Main reason for the trip. This bike path near the road has a bunch of "Pedestrian and cyclist only" stop signs that cars should ignore, however, earlier version of FSD Beta would brake for these little mini stop signs. 12.3, rightfully, just ignores them. A welcome improvement.
27:16 - Car does a couple dings, not sure why.
28:18 - Truck in opposing lanes, with blinking lights, is the truck I thought was a police vehicle pulling me over at 23:39. Also shows how Tesla navigation helps get you just a little ahead of traffic.
29:07 - Correctly remains in the right lane. Last time it did a jaunt to the left lane, then back to the right, it was messy. This one worked fine.
30:28 - End drive to Mellow Mushroom.
31:31 - Begin return leg
33:18 - Regression, possibly due to construction. 12.3 attempts to stop at toll booth instead of continuing forward. No disengagement, but I do hold down the accelerator. This is also why I compare 12.3 to driving like a tourist, because a Tourist might try to stop, while a local will be aware that you don't stop there. This is a temporary problem as it appears the toll booth plaza is being removed.
37:33 - Car is permitted to turn right on red, but does not. Historically it zooms up to the creep limit, but so fast that you disengage to stop it. This time it just sits at the red till green. Starting at this point, there's an SUV that rides my butt down the next road. This is relevant later.
38:50 - This is a spot that did lane drift in the past, it's been fixed.
39:45 - Roundabout, this one was handled by 11.4.9 as well, but it's much smoother now, les janky.
42:55 - Green light is staying green unusually long, making me uncomfortable, however, as it turns yellow, the car continues through, braking a little in the middle of the intersection. The car from earlier follows me through as well.
43:38 - The car that has been riding me from the earlier red light makes their move to pass, and catches me off guard. The car goes into the oncoming traffic lanes to zoom ahead, and take the left to get ahead of me. My mind was blown apart a bit at the brazen disregard to traffic laws.
44:43 - Begin unmarked road.
46:12 - Three vehicle interactions on unmarked road. One of them is while taking a turn, all were good, and natural.
47:27 - Stays stopped at this stop sign a smidge longer than it should have.
50:08 - Outro
