What I mean is that travel tesseracts experience. It explodes it to the fourth dimension. And it becomes dizzying to realise how many nows are happening all at once. To think of how many taxi drivers in every continent are talking into their radios right now. How many people are giving birth. Or eating a sandwich. Or writing a poem. Or holding the hand of someone they love. Or staring out of a window. Or talking to the dead.
