I think his concern is that it's unsafe because you might trust it when you weren't supposed to because it's too complicated to figure out who's in control at any moment. However, since the number of features is quite small, I'm sure owners will quickly get used to what the car does and doesn't do. The autopark and summon is surely going to run over far fewer children than human drivers do in those situations. That leaves just adaptive cruise control and lane changing. Well, if you forget to change lanes because you trusted the car, you still won't crash since the front crash detection (and your eyes) should protect you from that. So I don't see any safety issue there.
