IMO, far too much is being made of the nags and hands-on-the-wheel debate, especially in this thread.
(E)AP is a tool, nothing more. It can aid you with certain tasks, but like any tool, you can get yourself into a pickle if you use the wrong tool for the job.
I make an analogy to a table saw. If you have some plywood sheets that you need to saw in half, a table saw will help you a LOT. It can make short work of that job, and can make the cut a whole lot straighter than you can do with a hand saw. But there's some care you have to put into the process. As useful and quick as the table saw is, if you use it incorrectly you will lose some fingers. And that will be no one's fault but your own.
This is the way I treat TACC and (E)AP. It's a tool. It can assist me with convenience in certain situations, and is not appropriate nor very functional in others. I use it all the time in the former, and don't in the latter, which is the same thought process in which I'd use a table saw.
Table saws have some mandated safety features too. They have double electrical insulation, blade guards, and wood pushers. When you use one, you put on gloves, eye protection, and hearing protection. This brings the tool to a safety level that we, as a society, consider a low and acceptable risk. But even with all that, irresponsibility can easily circumvent all of those things and result in lost fingers and hands.
(E)AP is the same way. Tesla (or Cadillac, or Volvo, or Mercedes, etc.) can put heaps of safety features, interlocks, and restrictions on the tool if they want. In the end, you still have a fallible human moving at 70+ MPH inside 4000 pounds of steel. Without due diligence, potentially deadly things can and will happen no matter what level of safety features are present.
We can debate all day long about:
1. What we want (E)AP to be vs. what it is
2. What action (E)AP should take in a given situation vs. what it actually does
3. What design methods are "better" than others
4. What the philosophy of human-machine interface should be
5. Wanting/expecting autonomy level 3+ from an inherently level 2 system
Those debates, to me, are largely academic and superficial. You're the driver, you're in control, no matter how many tools and aids you use. Either you can drive safely, or you can't. (E)AP's presence, state, and function has little to with it.
