CB, at least here in the USA, is kind of dead - especially with the stupid "To FM" conversion so that Cobra/Dynascan/Cedar could sell new units. I can travel for 4 hours on I-70 and hear noting more than some blips.
Even the retard jeets that would clog 19 with that shit music of theirs are gone.
I remember it used to be "normal" to have a built-in CB in your truck/car/whatever. Especially if you lived out in the sticks.
Before cellphones and waze, yes - everyone had a CB.
I carry a handheld when I travel, but I rarely hear anything.
