Out in the "boonies" where there is no cell reception, one would be more likely to get help by doing smoke signals than getting someone on a cb.
The imagined security by having an obsolete device in a vehical is the same level of security a child recieves from their wooby. Lol
It would be a more wise endeavor to avoid being stuck out in the boonies by either not going out in the boonies or making sure that you are actually prepared to deal with and survive being stuck out in the boonies, i.e. making sure your vehical is in good working order. Having the proper, non obsolete gear to sustain yourself in the event that something goes wrong.
As far as their usefulness for traffic? A c.b. is much less useful than your eyes and experience. Often, the information you get from some chucklehead on the radio is completely wrong and can make a bad situation where there was none to begin with.
The last several years that I drove otr, I only turned my radio on at the shipper or reciever for them to let me know when and what dock to back into. That is because I figured out long ago that it was useless for any other purpose. The only drivers that had their radios on going down the road, had them on because they thought it would help them with traffic, because they had very little experience and did not know how to use their eyes. So, it would be absurd to rely on people with little experience and an inabilty to use their eyes, to help with traffic.
Stone in the stream. Once you understand that concept, there is no traffic that you can't deal with.
There is one other type that keeps their radios on while driving and those are "chicken truckers". They are the ones who are always speeding or running hot on their logs or both and are constantly trying to get "smokey reports" They are also useless and dangerous.
