You got that right. I'm from Georgia and when I bought a new car I had to get firm with the sales guy wrt no stinking stickers.
But I'm in CA now and no one has stickers; the tactful substitute is a "complementary" plate bezel with some dealer details on it (name, city). Those are subtle and I kind of like seeing where people are from.
Back in GA we have very legible county (2cm font) stickers on all the plates so that's how to geo-locate other cars there.
