I thought it might be a passive infrared (PIR) type, but I believe I heard it actually uses some sort of electromagnetic field disruption tech.

However, some (or all?) 2020 HTCs will set off the motion detector with the top down. My understanding is GM "corrected" that on the 2021's and later.

That is correct the sensor is supposed to be off with top down. My 2021 HTC works this way.

I returned to the car and put in my sandwich bag gently in the passenger footwell. I didn't touch anything on the car. Then suddenly the alarm went off. Somehow the car knew I reached in even without touching anything.

Whatever GM put in this car is pretty impressive.

Thats good to hear. If memory serves, that only worked on the C7 with the TOP UP?! Seemed odd to me, as the scenario you describe is more likely with a convertible that someone reaches in to swipe a bag, sunglasses, wallet, etc. when the top is down. Glad there is a motion sensor in play now.
