I have just as much experience ...
#1 - I've never experienced it doing 1 and even in the past week when I've had two examples of ambulances.
#2 is brutally bad. It almost 'randomly' changes speeds based on nearby roads (crossing over/by). I've had it change back to the wrong speed limit within 20 yards/meters of it just passing a speedlimit sign based on road segment (GPS?) data or some. AP speed limit was decent. FSDbeta is **awful**. There are 100s of complaints about this one.
Scott. I'm looking for another system that is comparable. Thats all.
Topics like this always seem to try and change subject into the evaluation/opinion of Tesla's product. Not really interested in doing that.
