Depends on the where you live ive found.

Lived in a few counties, and today i sat in Sainsburys carpark munching my lunch when a unmarked skoda octavia pulled in the space 2 down from me, thought here we go, as my windows on the front maybe a little too darkly tinted, and i fitted some sidelights that were advertised white but more of a blue, and my front numberplate i took off because it looked better

They just looked at me, got out there car, 2 huge bobbies, walked in front of my car, both took one look at it, one turned to the other and said ' tidy example that ' and carried on walking into the supermarket
