CB is better I think because almost anyone can get one be it mobile, handheld or base station and can be used immediately. Not everyone can erect a tower or have the room for large antennas. Or learn HAM, I am not interested in having to go through any federal documentation process. And I feel that that idea should be thrown out the window, unacceptable in this current state of times.
A car can have a concealed antenna or a removable one, its about keeping things local, I would like to have a long range radio setup but anything thats really going to affect me will have to happen nearby. I can offer no assistance to someone hundreds of miles away, but I can within an hours drive.
