My mind is aglow with whirling transient nodes of thought, careening through a cosmic vapour of invention...
Or I could copy your idea with a high quality scan/print of my local plate on a bumper sticker, keeping the real front plate in the frunk in case of emergency. It could even go over the vinyl wrap or bra to prevent paint damage.
Bwahaha!
That's not a bad product idea - custom printed car bra's.
