V12 is mostly good but after several days of use my biggest pet peeve has become its indecision around turn lanes, especially dual turn lanes. Not every intersection causes this behavior but when it does it will oscillate back and forth between lanes sometimes 2-3-4 times, or just kind of straddle the line taking up both lanes before committing at the very end.
Also I'm convinced the FSD driving profiles have zero effect on the e2e stack, including the "minimal lane changes" option, and only affects the legacy highway driving.
