You've noticed that same joke told by two different people, once works, and the other time doesn't, simply because how the person edits it. The silences, the pauses, what they neglect, what they emphasize - all of this matters.
We don't look at each other [in the car], but instead do so only when we want to. We're allowed to look around without appearing rude. We have a big screen in front of us and side views. Silence doesn't seem heavy or difficult.
