Just got 2019.8.3 last night on my Model 3. I've not been a fan of NoA or HW2+ in general. In past releases, I was delaying or cancelling majority of lane change requests. And then dealing with a lot of phantom braking and hesitation. But man, have to say, 2019.8.3 is pretty darn good. Did a 20 minute drive twice (once in each direction) with moderate traffic and a complex interchange (change lanes too early and you deal with several onramps merging into you; change lanes too late and you'll have a hard time with people letting you in). Lane change requests were perfect. No dangerous behavior. Very smooth. Overall, it's now better than some people I know. Might even be better than the bottom 25-33% of drivers which is a big step forward from before where I'd say it was previously unusable on this route. Well done AP team!
