In most countries, this is prohibited by law. While it might be interesting from a technical perspective, it does not help in practice.

Yep, and the overwhelming majority of people using them are not principled cypherpunks, but parking fee dodgers and habitual dangerous drivers.

Instead of a sticker like in the video make a stencil and spray diluted mud through it. Plausible deniability!

There were laws in many places where you could fight a traffic ticket because you couldn't plainly recognize a police vehicle, especially when a taillight or headlight is out, but now we pay for graphics to make them more invisible. "If you have nothing to hide, you have nothing to worry about." I like the plausible deniability angle, myself
