I pulled up behind a new C7 Stingray at a red light the other day and when I got within a few feet of the car my ALPs gave the parking alert and at the same time I saw 2 quick flashes on the back of the Stingray and when I looked at the plate closer it looked like he had a Photo radar plate blocker installed.

Just wondering if the ALPs set off his plate blocker or if this is totally coincidence
