This is the first time I've fooled with them and I can't say that I've ever known anyone outside of trucking that had one in a car.
I never would have considered one if I hadn't run up on them on the web. Seems a lot of folks have them or are considering them.
I rarely run into any other cars using them. Maybe the occasional PU but not many cars.
Just weird the way the internet seems to be keeping the CB alive...
