The Duke of Sussex displayed the switch on Tuesday during a special episode of Time100 Talks, hosted by himself and his wife, Meghan Markle, while speaking with Time editor-in-chief  Edward Felsenthal.

During the opening remarks for the episode on “the state of our digital experience,” the duke and duchess were asked to discuss how and why they chose the episode’s group of experts, which included Reddit co-founder Alexis Ohanian, with Prince Harry using “pop the hood” for a car metaphor rather than opening the bonnet.

He said: “When driving a car and all the warning lights are going off and there is smoke pouring out of the hood, you’re not going to keep driving, you’re going to pull over.

“Now, in the olden days, you could probably pop the hood, have a look under it and maybe perhaps fix it, or at least have a rough idea about what’s going on.

“But now, every single one of these new cars has a shield over the top of it. And it means you can’t actually fix it if you want to fix it, you’ve got to call the experts in.”

During the conversation, the 36-year-old elaborated on the importance of speaking with experts, explaining: “The online world is affecting the world. It is not restricted to certain platforms of social media groups. This is a global crisis.

“A global crisis of hate. A global crisis of disinformation and a global health crisis.”

Prince Harry’s use of the Americanism comes after he, Meghan and their one-year-old son Archie set up a permanent home in the United States, after announcing their intention to step down from their roles as senior members of the royal family in January.

After living in Canada for a few months, the couple moved to Meghan’s native California, later moving into a home in Santa Barbara in July.

While speaking with Felsenthal, the couple also touched on life in quarantine, explaining that they are treasuring the time spent with their son.

“All things considered, everyone is grappling with a different version of the same thing," Meghan said. "For us, we're trying to embrace all of the quality time we get with our son right now and to not miss a single moment of his growth and development, which has been really special.”

“This is an opportunity to spend more time as a family than we probably would otherwise,” Harry added.
