Not sure if the question is asking anything more than it's a real license plate from the state of New York. NY allows for vanity plates. Mine is using the default design background.How does it work when you drive in the corresponding areas? I'm guessing you don't have any issues with all the speed, parking and more types of cameras
If your question is the snow and if the cameras/sensors on the Grenadier get tripped up - they do. With ice I need to deactivate the proximity sensors. For roads, our municipality (in Buffalo) keep them pretty clear for the lane markers to not get too many bings and bongs. For heavy snowfall, the camera does get obscured so we lose the automatic emergency braking system and related systems.
