I installed a CB.
The wife could not see why.
After a detour last year that closed
part of the Alabama interstate for 24 hours
and being able to find fuel and other needs,
thanks to the CB, she is a believer.
I would think few hams are on the road.
Mainly due to licensing requirements and
equipment costs.

As far as cell sites being above the horizon, the opposite is true which is why they ALL are on low towers, poles or buildings. You cannot build an efficient cellular network these days from high sites, there are way too many users. While there may be high sites out in the middle of nowhere, they are the exception. Ham repeaters, and any reasonable base station can easily out perform any cellular node distance wise due to frequency and power.
Jeff nailed it. Also, some Ham frequencies can bounce off of the various layers in the earth's atmosphere allowing contact hundreds or thousands of miles away (almost like a fiber optic cable where the light is contained by total internal reflection).
We just took (and passed!) our Ham technician and general license tests. Now just a short wait to get a call sign and an entry in the FCC database.

The limitation of Ham, CB, FRS, GMRS is that the hand held units have their output limited to avoid damage to the user's brain. Need a mobile unit connected to the vehicle's 12v DC for power and an external antenna to get much range. Even then it is line of sight so OK for wide open spaces but not for wooded, rocky, or hilly areas.
