What are you talking about? Down in these here parts, that's a staple in trucks. They probably roll out of the dealership lots with CB's and whip antennas already installed as a dealer option!
Don't see a lot around here. Certainly not like a decade or so ago. I had mine set up for portability so I could move it from vehicle to vehicle but only used it when traveling. My cousins around the corner had a base station set up at home to keep up with my uncle when he was OTR. Even fewer Ham operators.
