Is it possible that those safeguards were deactivated by the Tesla delivery specialist, or by the customer at the suggestion of the delivery specialist, in order to demonstrate how the feature works? I genuinely don't know if that's something the delivery specialists do, but I think it's plausible. Tesla demonstrates Autopilot on test drives as a matter of course, and I could easily see them wanting to demonstrate Summon to new customers.
If so, I think it's possible the customer was not made aware of the safety implications and limitations of the system.
