They just might insist on taking the wrong route. Get stuck in traffic. And then get lost.
They might insist on taking the tunnel instead of the bridge. When you need the latter.

They might finally decide to drop you a few kilometres from where they had promised because otherwise it would be out of their way.
You might want to make alternate travel arrangements.
