2023.44.1 was pushed to my MXP on Tuesday and here's my assessment with regards to how it addressed the vibrations in my vehicle.
Initial vibration after sitting for some time: 75% eliminated
38-52mph vibration: 90% eliminated
80mph vibration: 80% eliminated
Honestly, I wasn't expecting much from the update but I'm happy as it's a drastic improvement to the driving dynamics. Hopefully, Tesla will continue to tweak but I'm very satisfied and driving is now much more pleasurable.
