Second set of drives in a row with zero interventions. A couple hours each. And this is on the 12.3 wheel eater.
Both drives were typical types of drives through suburban/exurban/rural roads including state highways, rural highways, county roads and city streets. V11 never performed this well. Not even close. I now expect no disengagements and few interventions.
12.3.3 installing now, so it should just get better.
While that last few drives involved no V11 stack, by intent, I really am awaiting the full V12 experience on all roads. Limited access on V11 is great - even sublime - but high speed rural highways often switch over to V11, which still suffers from the overreaction/high latency issues with things like cross traffic. This is a gray area between V12 city streets and V11 limited access roads that I run into on a lot of drives.
On the very good side, after driving several weeks on 12.3, I can clearly see the benefit of the NNs in reducing latency well below that of V11. Reactions to traffic cutting in, out, and crossing the vehicle's path are so smooth and human-like it's scary.
