Well here's a good one for you. It shows some good and some bad, but be sure to mute it. At one point, the car runs up to a construction worker with a stop sign, and it seems to want to go around until the worker steps out in front of the car, gesturing for Omar to move back into the correct lane (to allow oncoming vehicles to pass). Omar does nothing until an oncoming car appears, then he disengages.
From what I've seen in the videos so far, there has been some helpful tuning in 12.4, but no major improvements, and possibly some regressions.
