I received NOA for Model 3 with 2019.8.3 here in Germany.(Some people are not realizing that you must first be in Park, then go to the settings for Autopilot | Nav on AP and toggle NOA to the On position and acknowledge the beta status as a one-time action. If you haven't done this, you will never be presented with the NOA option during your actual trips.)
As for NOA in Germany without speed limits, I have to admit I'm not feeling confident with it so far, although I'm sure this will improve. But what I'm feeling so far, when I receive a request to make a lane change and I confirm it, the actual lane-change isn't performed quickly enough for me to feel comfortable with it. When I'm going 80mph (130km/h) and I confirm the lane change, but the vehicle's lane change isn't immediate, I'm left wondering for too many seconds if someone will approach me from the rear going 135mph (217km/h). Even in Mad Max mode, it was still slightly intimidating. This confidence gap sends me rather quickly into an inner-panic mode and I take over control again.
I think it will be excellent for speed-limited zones, but not sure how long it will take for me to love it in the speed-limit-free zones.
