I have a 2020 M3 on HW3 with v14 lite and it's very good. But even v12 was pretty good. I drove an HW4 as a loaner and did not notice a significant difference. I think the big difference would be on the long-tail of edge conditions, but I'm not sure.
There's a wide range of what people find acceptable. I think v12 was the last I tried on HW3 and it was bad. Inching into oncoming traffic trying to do left turns, extremely sudden and sharp lane changes, lots of interventions required. v14 on HW4 was the first I've seen it actually drive competently. I even got to try it in a couple snow storms and it did great. I did not try v14 lite, it's great they got it working in some capacity but I still wouldn't trust it as FSD because it's probably the equivalent of running a heavily quantized LLM (HW4 doubles the available RAM).
That's absolutely fair. I'm comparing it against v11, where I couldn't go a block before disengaging. And my routes and neighborhoods are relatively easy.
But still, even v12 can handle things like manual traffic signalers, construction zones, etc. The first time my car followed instructions of a cop waving us through a stop sign, I was amazed.
