Spectrum analyzers are cheap and common.

They’re gonna need to cheap and common if you want to cover 4.2 million miles of roads in the US.

Very few people are and will fuck around with felony and prison.

There are an estimated 19 million felons in the US, and nearly 80 million who have a criminal record.

Not my definition of “very few people”.

That might just be one lever above do your own research.

It would be great if you understood tech and had common sense, yes.

Alas…
