Can we say say something is going somewhere if it was delivered? [duplicate]

I don't think it's a stupid question at all.

You could say "the letter (is going/went) to New York," and the fact that it was delivered would be implicit, but that is largely because it is an inanimate object, which bears no potential for agency.

We could use a toddler as an example of a similar level of agency during delivery, i.e. "little Mikey is going to his grandmother's tomorrow." Still we find that the delivery would be implicitly understood, because a toddler's unaccompanied journey across town is not feasible.

But still, we could readily imagine a tortoise making its own way to a nearby river, so "the tortoise was going to the river" needs more context for anyone to understand that it was being delivered.

If you were to say that the tortoise went to the moon, that would be another matter.
