There has been a product on the market for over 15 months that provides a BT interface between any type of 2-way radio (CB or HAM) and its operator.

TalkSafe is a plug & play system. It utilises standard off-the-shelf BT headsets to provide PTT instead of using a hand-mic. This makes driving so much safer and offers compliance to any hands-free laws!

Dianese (Italian company) make helmets with bluetooth built in. So do Nolan, also Italian.

You can also buy an attachable bluetooth headset which fits almost any motorcycle helmet.

I think the Dianese will reach 300m, and possibly further.

When riding in a group they allow riders to communicate with each other.

"10-4 that smoky report, but heck... we got ourselves a convoy!"

Why do truckers still need CB when cell phones exist? 

There are alot of reasons, one major one: cell phones don't work everywhere in the US. There are large stretches of road out there where cell service is marginal at the best of times.

Europeans take for granted how ubiquitous cell coverage is in the "old world"

"You have a smoky on your tail!"

The best part of CB is you can warn everyone at once.

CB style chatting (or even standard 2 way calling) over a Bluetooth connection on mobiles would be cool (100m BT2.0 would be best). No cost to use, and the ability to chat to people around you just by searching for them on the phone.

Although, the only benefit I can think off, so far, is to chat to someone in the car in the lane next to you. Or in another room in the house.

"They even had a bear in the air"

"Pigpen got yo ears on"

Obscure, I hope not.
