One of my favourite scenes in The Warhol Gang — yes, I have favourite scenes in my own book — is a car chase in an underground highway system that runs beneath the mall. Well, technically, it’s part of the mall. Anyway, our hapless hero Trotsky is driving a stolen delivery truck and relying on the GPS to direct them to safety — the modern man’s prayer. Instead, the GPS drives them into disaster — the modern man’s god. I worried I might be taking liberties with the accuracy of technology here, but a couple of recent stories about GPS disasters reassure me that I’m writing nonfiction.

Remember, it could happen to you.
