> Mobile CB, $49.95. Ad says “You’ll never drive ‘alone’ again!” iPhone.

I mean sort of. CBs are still a thing that the phone doesn't quite replicate.

I would make the argument that the modern version of this is LORA/Meshtastic... Im sure at some point they will jam a few more radios into the phone just to have more features.

I like the comparison of Meshtastic being the replacement for CB, it fits pretty well since they are both decentralized and made to run without a lot of underlying infrastructure and both work well to communicate in emergency’s.
