I had to post this, because it was funny.
I had my car parked on the street, and I went out to move it back into our driveway. While I had the car on (which means the V1 is on as well), I opened the glove box and accidentally bumped my JTW laser tester that I keep in there. When I did this, my V1 gave me a laser alert! The front arrow lit up, so somehow, the V1's front sensor picked up the tester's signal coming from the glove box!
I guess this means, if a dwarf LEO clocks me from inside my glove box, my V1 will alert me!
