I did another drive today with v12.3.1. This was about 40mins worth, again around 4 planned disengagements with V11.
Overall, it handled the drive well. This route has two very difficult intersections with weird angles and less visible turns. Lots of traffic around this hour and V12.3.1 handled them very well. Both directions were zero disengagements, which was a surprise to me even with heightened expectations.
3 minor annoyances:
- I clearly see the difference between Assertive and Chill now, at least in terms of acceleration from stop/low speed. Assertive is quite a bit more forceful. So now I keep it in Chill mode. Even this one feels too strong for me in most situations. I wish if current Chill becomes the new Average and a new more mild Chill mode is added in the future.
- When it wants to switch lane, or if I trigger it through signal, it always hesitates very subtly then makes the move. It is also true that changing lane from left to right is now quicker, which is nice. Even when on Chill, I also observed that it changes lane, both when a slower vehicle is encountered in front of me on the right lane, or when another car is tailgating me on the left lane. I have NOT tried MLC, because I forgot.
- I'm still not used to auto-speed. Sometimes too fast, sometimes too slow. When it is too slow, tapping on acc seems to work, so I'm sort of ok with that. But I haven't figured out a way to slow the car down when auto-speeding too fast without disengaging. Anyone?
Overall, I still think v12.3.1 fixes 80% and broke 20%. For me, V12 is more useful, at least in v12.3.1 form. Just need to figure out how to get around the faults without adding much effort or stress.
EDIT : I forgot to mention that, during this drive, I had camera views on all the time to see if the car is close to the curves during all turns. At least in v12.3.1 in my drives, I didn't feel uncomfortable. Either this happens less frequent, or v12.3.1 at least partially fixed this issue from the earlier versions of v12.
