I'm at probably 2,000 miles in AP on my Model 3, and at this point, I feel like I'm very knowledgeable about where I can trust AP and where I can't. I do fear that people will give it too much trust in the beginning, and not try to learn how it behaves, because then, it's dangerous.

Dying in a Tesla is relatively hard to do, but getting hurt or even just totaling your car because you didn't understand how AP works is bad (and dangerous for others, too!)

I feel like maybe they shouldn't turn on AP until TACC has been active for some period of time, so that you can get used to the car and how it behaves. Even now, I am sometimes surprised (like the odd behavior when stopped traffic is ahead of you a ways, and the car right in front of you changes out of your line - your car doesn't notice the stopped traffic, so you have to stop yourself or you would slam into the stopped cars). I have to assume that, at some point, the front facing camera will supplement the radar and say, "hey, that looks like stopped traffic - I should stop", but I can understand, from a software development perspective, why that's a hard problem.
