No, it is absolutely not. I'm not sure why you keep posting this as if it is definitive.
Let me put it very clearly for you: it is not acceptable, in any shape or manner, to expect your users to have to "save themselves" from your product killing them every 5 seconds. If your product requires that, it is a bad product.
Furthermore, your entire argument of "it's just a level 2 system..." falls apart when you consider that Tesla jumps through several marketing hoops to deceive people and make them believe it isn't just a level 2 system. When you visit Tesla's webpage on autopilot [1], the first and only thing you see at the top of the page are the following words in big, bold text:
>Full Self-Driving Hardware on All Cars
>All Tesla vehicles produced in our factory, including Model 3, have the hardware needed for full self-driving capability at a safety level substantially greater than that of a human driver.
It is not until you get to nearly the very bottom of the page that Tesla displays a disclaimer that "when we say 'full self-driving', we don't actually mean full self-driving, because that would be illegal and isn't available yet." There is only one single sentence, buried within a paragraph mid-page, that says drivers must remain alert and prepare to take over. The rest of the page is also filled with language indicating that autopilot is capable of turning itself, switching lanes itself, speeding itself up/slowing itself down, etc.
It is not unreasonable whatsoever for someone to read this webpage and assume that autopilot will magically take them whereever they need to go. This webpage is in stark contrast to the reality, where autopilot will actively steer you into a concrete barrier and kill you if you do not babysit it. And to make things worse, Tesla apparently considers this to be a "feature".
According to your Twitter, you own a Tesla, so it seems you have a little bit of fanboy-ist bias going on here. I'd suggest you take off the Tesla fanboy ballcap and consider how you would feel if this were a different product. If someone sold you a smartphone, but told you "this phone never requires charging because it has a mini nuclear reactor in it. Be careful though, because if you don't keep your eyes on the phone at all times and press the 'please don't explode and kill me' button every 5 minutes, you'll die!" would you be defending that phone in the same way you're defending Tesla?
