From what C&D found in testing, and I've read in other articles, all the cars they used would shut down if the button was pressed and held. The Lexus model had the longest duration of just under 3 seconds but it did shut the car down. I'd be surprised if there's not a requirement that a car be able to be shut down regardless of motion.
