Dress up as a security guard and scan people. They won't suspect a thing because security!
Wauw, you managed to push all my buttons with a few words, you're a little Napoleon! Do you ever wonder what your employees really think of you?
I guess you hurdle sheep and micromanage the shit out of them, you probably don't have anyone in your team that really shines or anyone with a really strong character because you can't stand anything with a bigger ego than yourself.
Regardless of the drug test issue I wouldn't even consider working for you if you showed that attitude during an interview.
Such bad taste in design. Just look at it! LOOK AT IT!
Might not need vs does not have is a stretch. I would think all the information to determine if it's being tested or not would just be accessible by some main controller engine API. It seems the sensors needed to tell if it's being tested or not were really basic stuff like finding out if it's moving or not vs how fast it was being driven which could be required by the hand breaking system or a sensor to tell if the steering wheel is moving or not which could be required to turn headlights in the direction the steering wheel is turned etc. Excluding these build-in hardware sensors from a car that does not have extra options payed for by the owner might not be cost-effective when mass producing and reusing much of the same parts / wiring. Not paying for one of those options does not mean the sensors are not in place.
Some of the extra options you select when buying a car are software driven things with an extra switch in the console to turn it on/off. Not paying for it does not necessarily mean none of the hardware is installed or that none of the signals are available in the API.
