I have not read this thread but got 2019.8.4 last night. Feedback from today’s 80 miles of commuting:
Prior version: 2018.50.6 4ec03ed
2017 Model S 75D, EAP/FSD AP 2.0, MCU1
AP is super twitchy and feels nervous.
Lane division lines now seen outside of AP mode
Numerous braking events, am no longer trusting it. Prior version 2018.50.6 did not have these events nearly as much.
Instrument cluster locked up
HVAC controls having seat heat etc on the first page is a welcome change, would prefer old 8.x UI and camera on top.
Overall I am not trusting this version at all. It’s as if the car has forgotten everything and is having to relearn. It reminds me of how the car behaves in 2017, or worse. I have never had it behave this twitchy and nervous before. I also saw the car images on the instrument cluster spinning all around as if the car was dizzy and couldn’t track them. Very bizarre behaviour. (Car was stopped at a light). The neighboring car display early on felt rough/bouncy when it came out but in 2018.50.6 things seemed to calm down pretty nicely but this was absolutely bonkers today. The car images were literally spinning around in circles on the cluster.
