It does require human supervision while driving. Tesla makes this very clear. It's also all over the Internet. But there will always be people who do not get this. Those people should not drive Teslas, or pretty much any modern car for that matter.

Of course full self driving is coming at some point, but that's a conversation for another day. Meantime Tesla is making steps toward it very incrementally with things like the "stop mode" rolling out right now.
