Those that have phantom braking -- are you AP2.5? That has a different radar and its likely the whitelist is not working as well for AP2.5 as compared to previous AP hardware that used the Bosch radar. While the radar in AP2.5 is superior, it probably needs the kind of refinement that took almost 6 months with AP2 (still people have some issues but I've had none since April 2017).
Those that have 2018.14.2 a88808e and have driven with AP -- anything else to add to how this firmware has changed the driving experience with AP? It is helpful to note HW version (e.g. AP1, AP2, AP2.5).
I would think the AP2/2.5 experience would be getting better and better since the NN is continuing to mature but I also know Tesla can introduce regressions and it seems this release is finally going wide to AP2 cars and I would like to know what to expect before installing it (though I do welcome the new nav). AP1 has also been improving, so there is potential helpful information for those owners as well on what to expect with their first drive with the new firmware.
Maybe this is a release where nothing changes or they are subtle but usually, after 6 pages, there is some substantive feedback (AP2.5 fleet almost 1/3 have this).
