Nope. Radios didn't have the stigma of causing accidents that cell phones have, because they're generally operated by truck drivers, police and other emergency vehicles, pilots, racecar drivers, that sort of thing. They tend to not gossip. Wait, no, truck drivers will sometimes ramble over a CB, but there's a difference...
Most people give their conversation their primary attention. Their eyes will move with what they're saying, that's just wrong and bad. If your sentence trails off mid-word because you noticed something off the side of the road and lost your train of thought while you were paying attention to driving over talking, well so what?
When you're driving, driving is the Primary Thing You're Doing. All other things must immediately yield to the needs of driving. You can talk while driving safely, and most people either can't or won't, but it is a Thing That Can Be Done. Proof: It's a thing that has been done by many people for a long time, even in some pretty extreme situations.
