@JulienW I spent a bit more time with the speed limit blindspot weirdness and found something "interesting".
FSD is using the type of road to figure out which stack to use and is using V12 stack on 65-70 two lane roads, it only goes to V11 when its divided.
At least in this local Texas area, I can see it happen on roads that flip from two lane to divided and back. Its really rather annoying.
Can't test that until this weekend, but at least that will be with FSD12.3.4 unless they push another version
