He never thinks of turning off the ignition to shut down all systems.
While I absolutely believe this is a hoax, I can tell you that you can’t necessarily just “turn off” a Prius.
I had one as a rental car, and the first time I drove it, I couldn’t be sure how to get it into the equivalent of “PARK”, how to turn it off, and how/when to remove the ‘key’.
BUT if you have driven one for a while, you know what to do.
