I'm becoming a fan of V12 with 12.3.4. I've seen some very interesting and positive behaviors, like correctly selecting when to pass on waiting for a pedestrian to cross the street and when to stop & wait. Today, I witnessed a really amazing behavior. I had FSD engaged on a major multilane street when I encountered an intersection with traffic lights that had gone dark. I was in a lane behind another car before reaching the intersection, and I was fully expecting my vehicle to absolutely take off across the intersection after the car in front moved away. To my surprise, my vehicle stopped and treated the intersection like a 4-way stop like it should, waited its turn and then proceeded thru the intersection. The next intersection also had dark traffic lights, and my vehicle again treated it like a 4-way stop.
