"You seem very authorative in this thread, yet have nothing to support your claims." - Unfortunately, I can't back my credentials because of the stuff I've work/ed on. I can say it was a US company involved in automotive parts. "Stands up to 15 minutes of what? Smashing the side window with a crowbar? Angle grinders through the driver side door?" - Exactly the point I was making. They just hire a random number of hackers (not random obviously, but probably not much research into what is truly sufficient either) and leave them alone with the system for a few days to see if they can do anything to it. If nothing happens they get a pass. It was literally a case of getting a tick in the right box. "Who hires them? What sources do you have that say this?" - The place I work/ed. I need to see if the specification are public. I checked with an old colleague and they weren't sure if they published them - so they are now checking themselves. They agree that it was Government defined, but now I'm interested in finding out who else had to adhere to that.
