People here are sensitive about their licence plates. On Hungary's biggest used car site Használtautó.hu almost every car's plate is blocked, blurred or removed.
I'd say only about 50% of them is covered, sometimes with the weirdest things possible (like a wooden beam, and my favourite was the photographer's foot in sock+sandal
) Otherwise yes, many people are shocked if someone finds out their plate. Especially in a town like Vecsés, where most inhabitants are not the brightest (as GR20 told me)...
