What is this? Black rectangle sticker top left windshield

Back when i had my bmw, a dealer i went to had these crazy ultra fast garage bay doors that open and close when a car approaches, something about being able to have AC in the shop without wasting money by having open bay doors. You had to have some sticker or tag, rfid probably in the corner of your windshield and the bay door would only open if they were expecting your car.

Highly doubt thats what this is, but rings a bell.

 

Its a Russian listening device.

 

It's to protect your eyes during the eclipse on Monday. Don't take it off until after.

 

This happened to me once. Once being the key word.

 

It's a secondary Go Pro mount. Just in case you used the primary one.

I find the mount the most useful part of the truck...just after the left side drivers cubby.

 

the manufacturing plant I work at has these doors. They're cool as shit. Linked to a chip in our employee badges. I give tours to guests decently often, and like 90% of them make some comment when we walk through the first door and it just *ZIIIP* enter through *ZOOOP* 's.
