I'm very happy with the performance. I use FSD everyday. It is very very good. I only intervene when I want to. In my last generation hardware, that runs on a 144 TOPS computer, it will very occasionally (twice in the last 4 months) do something like start moving a few seconds before a red light turns green. These critical interventions happened all the time a couple of years ago, but since the introduction of V12 software have been all but eliminated.
FSD is literally improving exponentially, looking at it in Europe (where it is blocked by regulators with economic incentives to delay Tesla's progress) is like looking at a fully fueled rocket ship at ignition and complaining that it is not moving.
Go take a ride in a new Model Y with hardware 4 and V13 software in North America and you'll realize how the EU regulators are screwing over European customers.
